Gray screen and PC reboots
As in the previous part of the game, I have a problem. As soon as I start playing, it takes a few minutes and I catch a gray or other color screen and my PC restarts. It has nothing to do with any specific place in the game. This ♥♥♥♥ happens absolutely randomly.

I have already changed the power supply scheme, tried to changed graphics settings and updated the video card drivers.

I play on:
AMD Ryzen 5 3600
MSI Armor RX 570 4GB
16 GB RAM
500 Watt PS
The game is set to hdd

The color screen before reboot makes me think it's a GPU issue, but a PSU that fails to properly power a graphics card could also cause that. Also the fact it's random makes me think it's not a heat issue, but power. Is there any way that you could temporarily install a different PSU, even if a bit older?

Speaking of PSU, I didn't like the 500W. Should be enough but I would prefer a 650W. Just IMHO.

how old is your graphics card? it might be going out on you

Unfortunately, I do not have another power supply unit and speaking about problems with the video card, I do not see such crashes anywhere except in the subnautica series of games. The same Rdr2 or another "heavy" game works without problems.

As far as I remember it is 2017 release

You've almost certainly got a hardware problem. If not every game triggers the system crash, that's great-- you can play those instead. However, if you want to play Subnautica, well, you'll need to get your hardware fixed.

To confirm, try running Prime95 + MSI Kombustor or the older Furmark stress test.

If you see any GPU artifacts being reported by Kombustor, your GPU is borked. If you get a system reboot, your PSU is marginal and high load causes the voltage rails to sag below tolerance.

I ran through Kombuster and Furmark for a couple of minutes (10min) and nothing out of the ordinary happened. No artifacts, no blackouts. The maximum temperature of the beat is 78 degrees

Turn off auto restart so you get a system halt (BSOD) instead.
There will be a error code on BSOD. Write it down and look it up at M$.
Should lead you in right direction.

Even after disabling the automatic restart, the PC restarts. Just a gray screen, stuck sound and restart

I know you mentioned this happens only with subnautica, but this is starting to look more and more like a power issue :3

Unless you only plan to play Subnautica for less than ten minutes at a time, you might want to run the test a little longer. Still, this suggests your GPU is OK and the PSU is at fault.

To confirm, run Prime95's self-test at the same time as you run Kombustor. This will place load on both your CPU & GPU, and that combined load will test your PSU.

Well, I started both, and this whole turbocharger drove air for 15 minutes (this is more than enough because the subnavtica takes off in 5, 3, 10 minutes ?, it certainly didn't work for more than 15 minutes) and the PC passed the test calmly, yes the temperature on the processor was 90 degrees and on the card 70, but nothing, no errors or artifacts, everything is fine

Thanks for testing, although only running the test for ten or fifteen minutes is not long enough to give me confidence. (You stopped before your system fully heats up.)

If you ran it overnight and confirmed things remained stable for 8+ hours, that would be more meaningful. Anyway, if this was my computer, I'd pick up a 650W PSU and see whether that made a difference.

What is your AMD Radeon Driver number as Ive narrowed it down to a driver issue?

I was running 21.5.2 and BSOD'ing on Subnautica and Subnautica Sub Zero (and the driver died so badly Windows 10 refused to load it after every reboot); and I have a 6900xt and a 1200watt PSU. Every other game including RDR2 runs on Ultra at high fps 4k no worries for hours. Im rolling back to previous drivers now to see if i can find a stable one.

I have version 21.5.2, but it doesn't affect the game in any way. In short, my problem was solved very simply, even though it took several days to find this solution. Just add -force-opengl to the launch settings. In EGS, this item is located in the settings section and at the very bottom you select the game and register there, on Steam you go to the library, select the game, click on it with the right mouse button, properties, general and register there. At least after that, Subnautica BZ did not crash (only once when I first launched it, after about 20 minutes the monitors went out and nothing could be done, but on the second launch everything was already OK)

In general, this game has serious problems with optimization and bugs, because in 20 hours I found as many "jokes" as I have not seen in Cyberpunk 2077. Oh, and even after prescribing this command, performance drops, but at least it does not crash (I had about 40-50 frames at high-medium settings).But despite this game I liked it and I do not compare it in the previous part because I haven’t played it yet.
