Fair enough point, I can imagine that the lower lobbies have gotten exponentially worse

@David Perel I agree. The racing is better quality in the higher levels. When having a 99 SR meant something, even 'A' lobbies were filled with fair and competitive respectful racing. Now, that's no longer the case on average in A or below. At any rate, look forward to hearing your plans for the irl racing season.

I don't agree, the penalty system is frustrating but the game is still one of my favourites. The higher the lobby the better the quality of racing. I've found this to be true of almost every sim I've played online.

Hi David, loving the channel and videos, please keep up the good work. As a sim racer of about 20 years and a keen track day driver for 10 years, just wondering what your thoughts were on what sim/game has the most accurate circuits? I've used Iracing's Oulton Park in the past which I found to be very close and I found Assetto Corsa's Spa to be pretty good as well. Would be interested to hear your thoughts. Cheers, Michael

Thanks David and appreciate your quick reply. Good to hear about ACC tracks. I've not tried it yet but have many years of AC use. Interesting about GT Sport as well, not sure if they are laser scanned either but great to read they are pretty accurate. Thanks again for your feedback. Best wishes Michael

Hey Michael, thanks for the comment! It does depend on the sim, Gran Turismo does an incredible except for big sausage curbs which they intentionally dumb down for reasons I don鈥檛 know. iRacing is OK but many of their tracks are out of date. ACC seems to be doing the best job at the moment, they seem to be taking a lot of care with their modeling.

You can clearly see that you take the corners like in real life in GT Sport. And the right gear. You can't in Iracing and ACC. So for me, GT Sport comes closest to realistic driving. Just so it is said. I love the ACC. Iracing is for PC nerd,s with a lot of money ;)

How much impact do the wing settings have on fast tracks top speed?
David Perel
David Perel Hace un mes
The answer is 鈥渋t depends鈥. For example the 488 GT3 with the 2016 spec rear wing had a huge gurney flap which cost us a lot of top speed but added downforce. Then in 2018 they launched an Evo package which was like magic, smaller gurney, more top speed and more downforce. With the 2018 wing we don鈥檛 see that much cost in top speed when we increase the wing angle.

Thumbs up to get him to review Project Cars 2. I am curios of his thoughts, as well as other viewers thoughts on the game/SIM
SORA, and my pronouns are bleep bloop
Hello, can you please review Project Cars 2...?? :) The online is lacking at times, especially on PS4... But I am wondering your thoughts on how it feels, and where it ranks as a SIM compared to the others that you have reviewed..... I think Project Cars 2 certainly deserves a shot at a review. Plus they are working on a third one, and would love your input I am sure:) Thank you ahead of time

To be honest all 3 Sims are very good to watch, I'd say maybe ACC sounds the best but that's subjective, GT Sports Graphics stunning as always and iRacing with the better cockpit view, be interesting to know what your thoughts are DD with how each Sim compares on the feel of Spa ....then let the sim wars commence 馃ぃ compared to your Ferrari 458 lap I don't think any of the Sims nailed the raw sound tbh, ACC for me sounded the best!

What do you mean by "Is still a Playstation game"? What does the platform have to do with the realism and physics simulation? ...Please make sure you disable all driving assistance in GT: Some of those are ON by default like Active Stability Management (ASM) and they just turn the game into an Arcade sim for kids (as intended).

David Perel I guess computational application requirements, processing power needs and data bandwidth availability is still an unknown subject to most people.
David Perel
David Perel Hace un mes
@Mik S Top line simulators have multiple processors for each corner of corner of the car and then more to handle the aerodynamic rules and then more to handle the tire model. Graphics are the least important element when building a 'real' simulator. Trust me mate, the GT Sport does an incredible great job but it's severely limited by the processing power of the PS4.
Tintop Hace 2 meses
@Mik S omg.. lol. please stop.
Mik S
Mik S Hace 2 meses
Tintop Well, current consoles do actually have 8 core CPUs and at least 8GB DDR5 memory. There are still many i5 with less processing power than these AMD CPUs. People look at consoles, they see consoles ...and totally miss the computer inside. And again, the hard part is not real time physics calculations. More than 80% or 90% of all the available processing power (platform irrelevant) goes to graphics processing. Also, if you have two cores exclusively dedicated to tires behavior, then I assure you that most of their clock time is spent idling, waiting for something to happen. CPUs (wherever box they鈥檙e in) don鈥檛 work at car speeds.
Tintop Hace 2 meses
@Mik S it's not absurd. for example the SETA tyre model from pcars 2 uses 2 cpu cores of the ps4 for it's real time calculations... TWO cpu cores.... just for the tyre model. simulating stuff like suspension, aerodynamics, tyres, chassis flex, drivetrain oscillations etc needs a f*ckload of CPU power... consoles just don't have this so sims on consoles are more or less simplified to reduce the CPU load. That's why simracing as a hobby only really makes sense on PC (let alone the numbers of sims you get for PC and hardware). Having Assetto Corsa and pcars2 on consoles was really a tough job full of compromises.

Hello David, currently I'm talking with a lot of people about the seat/view position in the Forum. If you could make a Video about the seat/view position in real life of your car and show it in ACC, that would help/interest a lot of people. Just a small idea for a future video :) (because it's very hard to compare things with helmetcams, because they are mostly on the top or side of the helmet)

For a console game GT Sport amazes me and I find it very imersive.. Was hyped for Spa in the game and had the largest grin on my face driving it. Call it a Arcade game or a Sim, GT Sport has become my favourite out of all of them. No setup just jump in and drive. I would be a very happy camper the day GT Sport became available on pc, I can wish :D.. Great Video as always David love you content keep it coming.

the tire model of gt sport looks horrible
David Perel
David Perel Hace 2 meses
Because of the sound?
Skovsnegl Hace 2 meses
Taking into consideration that the real thing is what they are trying to emulate: ACC is a bit over saturated in color, the lighting inside the car is too bright, a bit better than iRacing but GT sport is more realistic.The car does move more around, using suspension travel and small dips in the suspension when cornering/braking and racing down the straight, you really notice the bumpy road and the G's the car experinced by tilting in corners. The road noise changes in the level of steering/tire scrub and gives a clear idea how much understeering there is and the sound with engine roaring, the curbs buzzing and brakes squeals is fantastic. Overall a better immersion of a real racing driving experince. GT Sport is better with the saturation of the colors, lighting in the car is better but the car seems to be flying on cushings, even when going over the curb on the uphill section. The suspension travel is somewhat there but you don't experince the G's the car is able to acheive. You notice it when it hits the curbs but overall it's low amount of feel of the speed. The road noise and the steering/tire scub changes like ACC, but that high pitched sound is not very realistic in a racecar to me, the curb sounds more dense and heavy, better than ACC but it lacks the braking squeal when braking but it could be that the 458 doesn't have ceramic brakedisc. Overall a more arcade racing driving experince. iRacing is the middleground when it comes to colors, the lighting in the car is worse than the rest, everything is illuminated and lacks depth in the graphics, nothing is shiny, only matte. There is some degree of car movement when braking and hitting a curb, but no G sideways tilt of the car taking a corner. Like GT Sport is a low amount of the feel of the speed. The road noise and the steering/tire scrub is bad, i've never like iRacing for that, there is no telling how much understeer the car is having with that white constant noise and the curb sounds like it's delayed/choppy and it sounds louder than it should be. Sadly like GT sport i can't hear the brake squeal which takes away the immersion of the game. It also seems like they are turning the steering wheel too much compared to the real thing and ACC and GT Sport. Overall a more arcade racing driving experince. They all got the dogbox transmission sound but that is the only thing they have in common, all 3 of them.

ClipApex Hace 2 meses
GT Sport looks like what real life looks through the lens of a GoPro not what real life actually looks like. One thing I'll give it is the sense of depth is great. ACC by default like AC is too saturated, I turn saturation down to 80% and the pallette looks much better. Another thing is everyone judging graphic fidelity from a compressed ESvid video is silly. The sharpest and more detailed game will always suffer most. I'm interested to know what settings are being run for ACC and iRacing. Love your content David, keep it up!

SheetFiber4488 Hace 2 meses
why set the sixth gear at a very small ratio? shouldn't we hit the redline in top gear for better acceleration?
David Perel
David Perel Hace 2 meses
Which onboard lap are you looking at? In real life the gear ratios cannot be changed, so your gearbox is designed to suit all tracks.
Kenny Hace 2 meses
Another great video Dave. For me GT Sport looked the best, I take it IRenting couldn't be bothered to paint the curbs the right color. IRL, GTS and ACC the curbs were correctly Red/Orange, in IRenting they were Red/White.

@Kenny you better don't drive Twin Ring Motegi in iracing.. it's shocking how utterly bad this track looks in iracing.. FOR THIS MONEY a real rip off

A couple of questions for David. Do you think it would feel more realistic playing anyone of these games with an actual motion sim rig? Also, your laps in real life seem to be 2 seconds faster than the Sims, is it because it's hard for you to tell how far you can push the vehicle in the Sims vs real life?
David Perel
David Perel Hace 2 meses
The only real lap that was faster was the Michelin. That鈥檚 purely related to grip levels. Whereas the Pirelli lap was very close to the sim times. I鈥檓 not a fan of motion rigs because they tend to have delayed feedback. I prefer a solid base with good FFB.

I鈥檓 not really sure, they all had some issues which I didn鈥檛 like but overall they did a decent job in different areas. If iRacing had a modern model of the track then I鈥檇 say they did a good job but until then... ACC holds the crown.

You always use 1st gear on the chicane except in GT you use 2nd. So do I, but I don't know why I'm doing it lol. Why don't you use 1st ? Also you lift Blanchimont on iracing but flat out otherwise, why is that ?
David Perel
David Perel Hace 2 meses
The 458 has more torque and first gear is shorter. In the 488 first gear is longer. Blanchimont in iRacing is not easy flat with the baseline setup. In real life it鈥檚 also not easy flat though.
Glen Waldrop
Glen Waldrop Hace 2 meses
One thing I noticed that was reinforced on this video, Spa on GT Sport is just too damned slick. It is slicker than it was on GT6. The second and third turns, you're just sliding all over the place. Even the real world has better traction than that.
Glen Waldrop
Glen Waldrop Hace 2 meses
@David Perel I've played it myself, back to back with GT6, sports medium is my preferred tire. It is slicker on GT Sport. GT Sport is slicker in general, even more so than real sims. GT Sport also screwed up the engine power adders. You almost universally increase RPM, GT Sport never does. They increase torque at the same RPM, which makes a 400HP Mustang Mach 1 unrealistically difficult to drive. That being said, I still play it often, I'm just acutely aware of it's limitations.
David Perel
David Perel Hace 2 meses
I was using hard tires in GT Sport. With medium tires it would have looked the same as the others. Not however that the perception of sliding is mostly to do with the tire noise aaaand the lap times are very similar to all the other sims. So it鈥檚 just a perception thing.
