So did you get to try out fsr2 ?
Yes, it yields as much as 33% more FPS in that sewer section I mentioned. I put it on Ultra Performance mode there and quite honestly, while the action is going on you don't notice the visual difference that much due to the slightly heavy fog effects. There's a lot of particle effects going on there, which as you say, affects frame rate a lot. I have to say though, even when it was running at 60-70 FPS, my shots still felt a bit slow, but I'm quite sure that comes down to this game's shooting animations being tailored more to survival horror than shooter style.
I ended up setting it to Performance mode after I got out of the sewers, due to FPS still dropping below 50 a lot. It's not ideal, but I hope to upgrade to at least a 4070 Ti soon. I guess what many are saying is true, that it still could use more optimization because the frame rate often wildly fluctuates. In many parts of the game, I can't manage 60 FPS even with Vsync off, so I turned it back on and set the frame limiter to 60. It tempers down the fluctuation a little, but not as much as I'd like it to. Still though, it's a TON more optimized than Uncharted was.
And BTW, I DID end up finding the option to restore default settings, but it didn't really help. So, in summary, I'm liking the gameplay WAY more than the performance of this game, but I do realize it's mostly because I'm on an older GPU of 3 gens ago. I have to say though I feel FSR 2 is a God send for those of us on these older Nvidia cards that do not support the new NV features. I also think HW Unboxed really should have mentioned FSR 2, rather than leave a lot of people feeling there's no way for them to enjoy this masterpiece of a game.
The only negative for me as far as how this game has affected me is it's had me so engrossed I've now spent two nights in a row staying up WAY longer than I normally do, so it's kind of disrupting my sleep and daily routine. At about 65 now though, I'm retired, so it's more a matter of how that afffects my health, than anything work related.
IIRC, shader recompilation may be required if changing hardware, OS, or drivers. Not always though.
Well now you've got me in an old man funk, because after you saying that, I realize I'm not 100% sure an OS or driver update wasn't the cause of it.
I had no issues running it once I lowered my mouse speed.
Are you talking about sensitivity or polling rate? I really need to know this because that might be part of what's affecting my shot speed, which is still a bit slow even with FSR 2. It makes sense though that a team like IG that works closely with ND on games that were originally made for console and now adapted to PC, might not be all that savvy on mouse scheme coding.
My logi G402 settings are 960 on sensitivity, and 1000 polling rate. I tried turning off raw input in the game's mouse settings, because it makes my mouse a bit too squirrely in a lot of games, but that didn't seem to make much difference. I'm still waiting for Digital Foundry to do an Optimized PC Settings guide for this game.
