RTX 2080 Super using very little VRAM

[magicrobots]

Hello!

Precursor: my system had been running wonderfully since I built it this spring. All of the issues described below began about 2 weeks ago.

 

When the new destiny expansion came out, it coincided with an nvidia game ready driver update. I installed em both, and started playing the expansion a couple weeks ago. Immediately the performance was terrible.

 

After some troubleshooting, I noticed when looking at precision X1 that when I set the game to max settings, it only uses 4GB of available 8GB of vram. If I decrease the game quality, the vram ceiling decreases. I've tried this with DOOM Eternal as well and it exhibits the same behavior.

Some additional info: the games are playable but seem to want to force themselves to ~30fps by only pulling the amount of vram necessary for that. Occasionally they'll drop to like 10 and become unplayable until I open a menu or wait an arbitrary amount of time during which I haven't found a scientific solution to wake up the GPU. This usually happens if I alt-tab to a youtube video or something.

 

My monitor is 120Hz vsync capable, and I've tried setting vsync to 120, 60, or turning it off. Doesn't seem to have an effect.

I checked the CPU load and it never seems to max out on any thread, and I have updated win 10 and tried rolling back my geforce drivers as well, to no avail. Any help would be appreciated I have no idea where to look next!

 

And yes, I tried my wife's suggestion of unplugging it, waiting ten seconds, and plugging it back in.

Did you roll back the drivers and test?

[magicrobots]

Yes I did! Exhibited same behavior with older drivers, so I thought it was a Destiny 2 thing until I tried DOOM and it continued to only use a tiny bit of vram.

Hm, I just noticed that in game, in Destiny when I adjust the video settings it displays the VRAM usage -- does this look off to anyone? 3196/8010 MB at max settings?
