Cyberpunk 2077 bottleneck

blakslee720 · May 16, 2022

Hello everyone,

After switching from an Aorus Master 3080 1.0 to an FTW3 Ultra 3080 (450w bios), I've noticed some horrid stuttering and weird CPU usage behavior in CP2077. At first, all my settings were maxed (except I used High instead of Psycho where applicable) with Balanced DLSS. But the problem persists all the way to Low Crowd density, RT disabled and balanced DLSS. I also am NOT using HDD mode because the game is installed on an SSD.

When I'm just walking around, or I'm indoors, it's ok. But when I get on a motorcycle and ride around the city, it turns into a stuttery mess. When off the bike, my cpu seems to bounce from like 35%, 65% and 95%, then start the cycle over, kind of in that order. Riding the bike, CPU is 70%+, spikes higher when it stutters and GPU usage drops.

The game is currently installed on an OCZ Trion 100 ssd and I've been thinking about getting a 970 Evo Plus (cause it's a million times faster) to see if that solves my problem.

Maybe it was stuttering on the Aorus master too but I didn't notice somehow? That was a 320w card, so the FTW pulling up to 450 is likely going to perform better.

Do you think it's the CPU, or is my relatively dated SSD, the more likely culprit? Like, it can't load fast enough when riding the motorcycle around Night City?

PS: my case airflow sucks so I leave the side panel off to keep the temps down.

Some GPUs stutter with some hardware.

My EVGA XC3 Ultra 3080 ti stuttered in CP2077 and Horizon Zero Dawn with my 5800x rig. With my i9 9900k rig it was fine. The 5800x rig got a FTW3 Ultra 3080 ti and was fine.

I did get the stutter to stop on the XC3 using vsync buy why the XC3 was effected and the FTW3 wasn't is a mystery to me.

I do not think it is the SSD since I have the games on SATA SSDs and are fine. My modded games only seem benefit from fast M.2s.

For anyone who comes across this in the future, I found a good deal on a Samsung 970 Evo Plus, moved CP2077 onto it and everything seems to be fine. Running much better. CPU still gets to 80%+ is really crowded areas (crowd density setting high). We'll see what happens with zen 4 before I make any changes to the CPU
