Strange performance

[Finnisher]

Hey so when I play this game, I'm having this strange issue where performance seems very solid for a few seconds after starting, or pausing and unpausing, but it then seems to drop down considerably, at times even by half. I thought it was initially anti-aliasing as SSAA is quite demanding and I was testing it out, but the same happens with FXAA as well.

Any idea what it is about? My frame rates are good when the performance is up, but only for that brief moment, it's like something unseen kicks in and it's quite jarring, but I'm not seeing what it could be.

This is old game, it's fine

Make sure to activate HiFi Simulation in the game settings. It basically unlocks 60FPS.

Actually no, it just enables animation interpolation so they don't look bad.

I'm getting the same issue here on a RTX 4090 and a i9 13900k. Dunno why.

Oh is that what it does? Hi-Fi is an audio term, they should have called it "animation interpolation" to avoid confusing literally everybody.

I actually gave up, opting to wait for some sort a fix down the line, wasn't in that much of a rush to play the game yet.

But, if anyone wants to investigate, I can say that I tried all sorts of combinations, including enabling and disabling HiFi simulation, nothing worked. I even restarted the game between these changes.

One thing of note however was that the issue seemed somewhat affected by Windows compatibility modes, or at least I perceived it that way. One of the modes (can't remember which one) seemed to extend the time in which the performance spike occurs, but wouldn't eliminate it outright. That's all I managed to find out before calling it quits.

Game will run on a potato if you target 1080p@60
If you're aiming for 1440+ @144 Hz then the game wasn't made with that in mind
Should run well on win7 and win10 and anything inbetween
Any newer and you might see something break
When in doubt, old (it's not THAT old) windows (it's a console game lol) games run best on Linux, ironically

I suppose. I can reach 60 fps no problem, and if there was no way to run it above that, I'd even accept that, but seeing how it seems to function extremely well for some time, but then the performance takes a hit for whatever reason, that's what's really bitter about the whole ordeal. I'll get back to it eventually, but I guess I'll just have to do with that performance when I do.

So it seems that 60+ FPS interpolation is broken on modern systems. If you press Ctrl + Home while in game, it disables interpolation at 60+ FPS and runs the game at a capped 60 FPS, and that seems to stop the stutter.

Make sure you keep Hi-Fi Sim enabled though, or else it'll drop the framerate to 30 FPS.

Also, looks like this always happened, even on older cards:
