Feels like FPS drops over time?

[reggie.ps]

When I boot the game and play a level at the start my FPS will be from 100-140; by an hour of gameplay or two; that will go from 60-80FPS.

Reboot and restart the game? Same area that I was getting 60-80FPS in? 100-140FPS.

What's up with that??

In Nvidia control panel I set V-Sync to Fast and it seems to have worked. In-game V-Sync disabled.

I would not recommend using this game's vsync. It adds a bit of input latency (although I've seen way worse in games like Homefront 2), and it seems to be unstable framerate-wise. Fluttering below 60fps for no apparent reason. CryEngine has a really bad history with vsync.

I'm fairly certain Fast Vsync doesn't produce tearing.

No it won't. Fast vsync basically only engages vsync when you hit an fps number that isn't native to your display refresh rate. So it eliminates tearing like regular vsync but with significantly less input lag. The only downside is in some games (well engines really) it can cause frame pacing issues although it's fairly rare.

Honestly you're better off using your cp frame rate cap combined with fast vsync. For this poo berry of bad optimization I'd cap to 60 even when using DLSS if you can.

Fast v-sync drops frames above your refresh rate,
Its always active.

Guys; I'm failing to see how VSync is relevant to this; I never use VSync as I've got a 144hz panel and I rarely see ghosting; especially in newer games. I don't have VSync enabled in game and I definitely don't have it enabled in my Nvidia settings either, I have it set to "Use the 3D application setting" because I do need VSync in cases like Dead Space 1, but other than that I will easily refrain from using it.

Can I know why you guys are mentioning VSync?

VSync shouldn't have anything to do with this issue.

Had the same experience playing the game, 144fps after loading, then after a couple minutes 90-110fps for about an hour, then performance went to hell and I only got 60fps, floaty movement, input lag and even drops to 30fps.
Granted, my setup isn't ideal for demanding games
(dual Xeon Workstation with 2x 12C/24T@3.5GHz, 128GB ram @ 2133MHz and a RTX 2080 non-Ti) but it's certainly not a potato.
According to the log file the game detected both cpu nodes / all 24 physical cores of my system, but obviously didn't use them. ( Ironically, it was not able to detect my Zotac 2080 AMP, but decided to use the highspec preset anyway. GG Crytek )

During framedrops the Afterburner/RivaTuner OSD showed that GPU load also went down, not up, while CPU load was constant at 10% at all times.
Basically a serious CPU bottleneck. The game max'd out four cores and didn't use the remaining 90% of available compute power it knew was there.
After 90 minutes the game crashed and wouldn't start again, it kept minimizing the window to the taskbar everytime it tried to switch to exclusive fullscreen.
Uninstalled and refunded it. It's a crappy 360 port with some shader tweaks to allow raytracing. That's literally what this cheap cash grab is.

Anyway, I didn't have enough time to figure this out ... but I can think of one option that might help with frame pacing and overall performance.
NVidia's Low Latency Mode, which drops the number of pre-rendered frames down to 1 and in most cases significantly lowers CPU load. (set it to "ON", not "Ultra" !).
Is it also the magic bullet that prevents this mysterious performance degradation over time? Who knows... ^^

I got this advice from https://www.pcgamingwiki.com/wiki/Crysis_Remastered
in the "Issues fixed" section "Low performance with CPU and GPU usage below 100%"
