My take on the physics and general ramblings, PART 2 (
PART 1 here, I suggest read that first otherwise some things here won't make sense).
Currently at Menu Book 13. Finished all licenses and missions with golds (well, the non bugged ones at least).
1) Pad vs wheel - IMO people should really state what control input they're using here. I just tried GT7 with a pad the other night and it's like a completely different game. You really cannot compare the physics with a wheel. There has always been hidden stability assists with a pad, but this makes the difference with a wheel more apparent in GT7 because of the oversteer issue. If you notice the HUD red dot steering indicator, with a pad it's not quite 1:1 with your input. There's a slight input lag and steering angle limitation the higher your speed goes. It acts like a "hand of god" that stabilises the rear end, and thus makes the physics a lot more manageable. Keep in mind I haven't driven GT with a pad since switching to a wheel in 2008, but I can instantly almost match my wheel times in license tests with RWD cars.
2) Tyre pressures (or lack of) -
@Scaff I think in your early review video you mentioned the lack of TP is what might be causing the weird oversteer. Taking the R34 @ Maggiore example from my first post, I tried the same combo in Assetto Corsa (for those not in the modding scene, yes we have Maggiore converted into AC). Stock street tyres, no aids, first with minimum pressure (15 psi), then max pressure (47 psi). You do get more oversteer with max pressure, but the effect is still nowhere near GT7. You can be an absolute tool in AC, see sawing at the wheel, and the car is still saveable. In GT7 if you even use more than 25% throttle there is 90% chance you will loop the car. It's like a traction circle that's had its acceleration half chopped off.
3) Comparing the exact same combo again but in GT Sport - basically from corner entry to apex I prefer GT7 (better load transfer, suspension more free, less understeer). But from apex to exit I prefer GTS.
4) Driving aids - initially I was throwing everything in GT7 to make the car behave (TC1, ASM, CSA Weak). Keep in mind normally I only drive with ABS in GTS (and Factory settings in AC). Now I've weaned myself off ASM and CSA. TC I still sometimes use on a case by case basis and honestly, I'm fine with that. As many have said the TC is much improved in GT7 (though still not on the level of AC/ACC) and modern super/hypercars/GT3 cars are made with TC in mind. However, there are times when even driving 200-300 hp cars the rear end breaks loose excessively without TC. I CAN control it, but it's just silly and shows the physics need work. I've driven a GT86 on dirt in real life (TC off), and the rear end is more planted than this car in game on tarmac with SH tyres.
5) Default tyres - I noticed PD doesn't just stick SH on every road car now. Old cars use CH/CM, most street cars use CS, and only sport/supercars use SH 👍 It's a step in the right direction, though I still would prefer a true "default" tyre with their actual brand like in AC.
6) Tuning - lots of people mention tuning or buying parts to cure the excessive oversteer. Personally I don't believe we should be doing this to compensate for the game's inherent physics flaws. I never tune in AC beyond just tyre pressures and all the cars handle just fine. Also most cars on the road are not tuned, and people don't just spin in every hairpin or roundabout.
7) Aquaplaning - I think SvenJurgens posted that video of the HSR Mission race where he lost the car on the main straight without any warning. I experienced this also and while the effect is realistic, IMO the lacking FFB in GT7 makes this situation more hazardous than reality. It's more akin to black ice than water. In ACC I can feel when I hit standing water because the wheel would get light and start to wander a little. In GT7, you're just gone. I can feel hitting puddles (I can also see it lol), but until they fix the FFB it's just too much of a lottery.
8) Bottoming out? - in one of the Mission races with Chaparral 2J at Sardegna A, I lost the car completely without any warning on the high speed kink after the first turn. Now this is a ground effect car on steroids, on racing slicks, and I was going 200+ km/h at that point. No way should the tyres break loose in that situation. There is a slight dip in the road at that point so I suspect the car is bottoming out and the exaggerated weight transfer issue (same as the rally jump landings causing all sorts of weird ****) caused me to lose control. Another thing to fix/tone down.
9) Aliens - no, not the UFO kind. I see some people using the top drivers not having problems as an example of nothing is wrong with the physics (even though people like Tidgney and Super GT have complained at some point). Honestly these guys are too good to be a yardstick. You can give them a car with reversed steering and they will still find a way to go faster than us mere mortals. You can be fast in Mario Kart, but that doesn't mean you understand car physics and how things relate to real life (extreme example). Of course you can't take the impressions of a DR D driver either. But just because someone is only DR A/B doesn't mean their opinion is less valid (especially if they have long experience driving on the limit IRL).
10) iRacing Lite - there's that video comparing iRacing vs AC, and that's is exactly how I feel with GT7 at the moment. GT Sport tries to copy the online mode, well now GT7 has copied the physics of iRacing as well (14 years late no less
). The base is realistic, but due to legacy quirks with the tyre modelling, it can result in some weird behaviour over the limit. Racing is about keeping the car at 99-101%, and despite what some people say there is still some adjustability once you're over the limit. But in GT7 atm you are basically forced to drive at 98-99% because anything over, will result in certain death. Sadly, iRacing has gaslighted an entire generation of simracers who don't know any better, and I'm afraid GT7 will also do this unless PD fixes things quickly (mega doubt).
Anyhoo, I'll just close by saying that I find it ironic the Physics guy (same person since GT1) and AI programmer shows up after Einstein in the GT7 intro. PD do have a sense of humour after all
