I remember this happening but 8 months ago and was fixed around that time with a game update. I am testing (not with your save game) with 4 save games I have. I have everything on max on a 4090 and a 5090. Did 30 minutes each for a quick test. Both cases worked.

I also just tried today too with a 4070 and worked without issues. The 4070 was at 1080p if that helps at all while the 4090 and 5090 were at 4k (13900k and 14900k cpus)

I can confirm that this does not impact Ampere (Nvidia 3000).

You should try running my save file, it could be a completely different bug than what happened 8 months ago. I'm of course using the latest version of KCD2. Can you try opening my save file on your 5090? All settings on Ultra.

It would likely be better to report it directly to Nvidia. None on the devs or affiliated testers have a 5000 series GPU to confirm with.

Okay give me 2 hours.

I dont know if my technical report for your case ever got on time for the 1.5.2 (I doubt since it was less than 10 days ago) but here is my report

After loading your save game, 2 seconds later it crashed. Using dmesg I got this:

[ 3907.780798] NVRM: GPU at PCI:0000:01:00: GPU-13c44046-56a6-74ab-e364-6dafc4f7b478
[ 3907.780815] NVRM: GPU Board Serial Number: 0
[ 3907.780818] NVRM: Xid (PCI:0000:01:00): 109, pid=27590, name=Main, channel 0x00000015, errorString CTX SWITCH TIMEOUT, Info 0xc014

My honest opinion: This is one of those game related issues. Even if it happens on Linux and not on Windows, testing for what I could around 100 other save games that I have (for some reason it saves anything I do to a file) and none of them froze the game in 10 seconds of testing. I got a hunch if you play in another save game or start from scratch with the 1.5.2 it would fix the issue.

Thanks for testing! You can also try setting Global Illumination to "High" or lower and the freeze will not be reproducible.

So this confirms that it's not just my PC and anyone with a Blackwell GPU can reproduce the freeze with my save file.

Considering this is only reproducible: on Blackwell, with Global Illumination on Ultra or higher, and on Linux -- I'll assume it's an issue related to Proton or vkd3d-proton, or Nvidia drivers on Linux. Maybe a wonky shader compilation crashes in that particular location?

I'll add that it's not just this save file. When I was playing in that general location, getting close to the camp froze my game multiple times. This save file is just a really good example because it just freezes in 2 seconds without you doing anything. I have other save files not far from that location that still freeze the game when you try to get close to the camp. Something in or around that camp just crashes the GPU pretty consistently.

Does that GI setting utilizes DXR? I had similar issue in another game with DXR GI (nvidia's RTXGI) enabled (#2599) and it only happen on ampere (3060, both desktop and mobile). In such case you should report to Nvidia.

Cryengine's SVOGI in this game doesn't use DXR.
