All 3D games crash after a minute or so

[CatnipChloe]

I've been trying so hard to fix this. I've got a 5900x on a 360mm AIO, 64GB of 3200Mhz RAM, and a 2080 Super. My games are all on an NVMe SSD. Subnautica crashes anywhere from 15 seconds to 5 minutes of gameplay, Below Zero does the same, BPM: Bullets Per Minute crashes with "Unreal Engine is exiting due to D3D device being lost", GTA V crashed with "D3D init issue", Phasmophobia crashed, playing Beat Saber in VR ends with the headset freezing up entirely after a while and requiring a full restart.

Terraria runs no problem. Running SNES games on an emulator is fine. Modded Minecraft runs fine.

I've had this system for about a year. All these games used to run fine. I've tried: Rolling back the GPU driver one version, rolling back the GPU driver two versions, updating it again, clean installing it, rolling back Windows updates, reinstalling Windows updates, completely deleting Subnautica and reinstalling it clean, running it with -dxlevel 81, running it with only cores 0, 2, 4, and 6 enabled for it via Set Affinity, running a memtest on my computer (no issues), watching thermals while playing (stayed a steady 68 degrees celsius the entire time until crash), running a GPU benchmark (Unigine Heaven completed a full nearly 5-minute run with no issues, scored 4422).

I'm rather lost at this point. Everything I see points to some sort of driver issue with the GPU, but I even tried rolling it back to the February driver and the issue persists. I did a complete clean install of the GPU driver, meaning full uninstall of the current one and install of the new one. Clearly, something is screwed up, but I'm clueless as to what my next troubleshooting step is.

Might actually be hardware related. GPU could be going out but I wouldn't rule out a PSU issue either. Does seem as if the GPU cuts out when it needs to start drawing power.

[CatnipChloe]

Doesn't seem like any sort of power issue. PSU is a 750W EVGA 80+ gold, and again, I ran a full benchmark/stress test on the GPU with no issues popping up there, at least as far as I can tell. I'm concerned the card is dying, which is really unfortunate especially with the 4000 series just around the corner. Maybe I can limp it along or something. I don't have a backup card to test with to verify that it's the card, because I got this one as a replacement for a previous one that was fried by a faulty AIO.

Edit: You might be right. I just checked, and Minecraft never pushes my GPU over utilizing maybe 40% of the GPU, whereas all those games pushed it to 98%-ish.

Quick update for everybody curious about this:
Spoke to EVGA tech support with a full list of the tests I've run and the error messages and behavior I've seen. Their response was "yup, looks like the GPU is failing, let's RMA that sucker."
