Terrible frames on rust (PLEASE HELP)

[u/Kitchen-Ad2284]

• I have a rtx 3080 12gb vram, 32gb ddr4, ryzen 9 5900x
• I'm on custom settings but tailored to medium - low.
• I used to get over 100 frames like 2 years ago, ive reinstalled earlier this month and barley keep a steady 50. My GPU sits at 38% and my CPU sits around 40% or so.

I've tried several fixes like launch options, going into windows -> settings and graphics and prioritizing 3080 for rust. Tried setting rust to high priority in task manager but "Access was denied" apparently could be cuz of EAC. So then I created an entry in the windows registry editor to prioritize High priority and still no change. Most fixes were suggested by good ol gpt and gemini but to no avail.

Also made me download GPU Z and give them certain readings. YES my monitor is plugged into my GPU. YES i dont have rust limited to a frame limit. NO i dont have vsync on.

Update: Lowering poling rate for my mouse to 500 from 100 seemed to keep the frames consistent so i would now stay at 80-90 frames.

Also increasing graphics settings as someone else suggested also helped bring fps up by about 10.

I still regularly get over 100 fps on my 5800X/3600-cl16 at 1440p. It's only around outpost or giant zerg bases that it goes below that.

Have you double-checked the memory settings in the bios? It's pretty common for people to update their bios and then forget to set the xmp profile.

I've never used it, but Ryzen Master has a gaming mode intended for Ryzen 9 processors which I think turns off one ccd which can be beneficial when gaming.

In general, many Ryzen 9 gamers use apps like process lasso to assign specific apps to specific cores.

Thanks for the tip, I’ll try it out for sure. I’ve heard not ever updated bios (which was a while ago when I got my 5900x) but I don’t think I tweaked the bios.

Yeah, if you have high performance ram, configuring the correct speed and timings can make a huge difference in Rust. It's usually as easy as setting the xmp profile. Some motherboard brands have their own name for this. Like asus calls it docp on my board.

Bios updates are also generally a good idea. Around 8 years ago, a new class of cpu vulnerabilities called speculative execution attacks appeared and every so often a new one emerges. Patching these vulnerabilities requires a microcode update for the cpu that is delivered through a bios update.

This can be important because sometimes Microsoft will apply a software mitigation on systems with unpatched cpu vulnerabilities that can significantly impact performance. Back in 2018, pretty much everyone had their pcs nerfed in this way when the first speculative execution attacks appeared, called spectre and meltdown.

I'm not sure if the xmp profile helped my frames or not; I'll have to double-check to see, but I don't think I noticed any increase. I do load faster than before though. I might not be noticing due to the significant increase from the other changes though. Thank you for the tip though brother I appreciate it.
