Higher than usual CPU usage (and in turn, lower FPS)

Issue Description (Required):

Sometimes when in a mission/mourningstar/psykhanium/mortis trials, my FPS would be much lower than usual (usually I get 30-60 less FPS, but rarely even more than that). When this happens, my CPU usage goes up dramatically (normally in missions, it would be around 60-90%, but when this happens it’s a flat 100% CPU usage). A fix I found that worked twice was getting a penance during a mission, restarting also usually fixes this issue.

Attempted Solutions (Optional):

Changed every graphics setting, updated drivers and disabled all mods.

Platform (Required):

PC - Steam

[PC] PC Specifications (Optional):

CPU - Intel core i5-9400F
GPU - NVIDIA GeForce GTX 1660
RAM - 16 GB DDR4

Upload Supporting Evidence (Optional):

Have you checked memory usage? If you’re running out and hitting the page file it can appear as high CPU usage.

That’s how i spected a 9400f to work, i have a 10400f and works as the same, don’t spect it to get better, but u still can lower the graphics that affect cpu the most (ragdolls and lighting/shadows).

GPU memory does run at it’s limits when I play for like 2-3 missions but RAM itself has 4 GB available. I’m gonna try running the game with very low textures and see if it occurs again.

Everything except textures, light quality, bloom and ragdoll interaction is on their lowest setting. Textures are on medium and light quality is on very low.

Still happens with 2 GB of VRAM and 5 GB of RAM free on very low textures.
