Had some time with 2.0, it's......fine I guess. Visuals are slightly sharper, lighting is slightly better, AI still sucks, career mode is still barebones but with a new dress on, the new tyre model is fine, doesn't do anything revolutionary, just better than it was.
LMDH, I don't understand what they're struggling with in this class, but every other game that features these car, has done a significantly better job, in PMR they just slide all the time, Eau Rouge is taken at some sort of constant drift angle, rears lock way too easily, corners consist of rear locking, catch the slide, understeer, no feel, snap of oversteer and a constant slide angle. Same goes for any of the faster classes in my experience, GT1, LMP, Group C. Have they improved? Yes. Are they good? No. LMU, AMS2, iRacing, even Rennsport, do much better jobs with the LMDH and respective faster cars. Yes, most of these games are only on PC (my PMR testing has been done on PS5), but they are still the comparison points and PMR is a long way behind them. Rennsport is the only real equivalent on PS5 aside from games that preceded them such as ACC and GT7 to some degree. Whilst Rennsport has its own long list of issues, it does have decent feeling physics in comparison to PMR, the LMDH, GT3 and other comparable classes feel better and more like what the other sims feel like. That's not to say the other sims are 100% accurate, but they're certainly more believable than PMR.
My main racing fix will remain Automobilista 2, it just does a better job across the board, if you're on PC, I still can't see a reason to buy or play PMR over any of the other options. If you're on console, it's obviously a different story, with significantly fewer options, but I'd perhaps hold out for the next big Rennsport update and see what the reception to that is like, it's entirely possible in my view that it could surpass PMR.
