VRAM-limit-related crash - GTX 690 at QFHD (3840x2160)

Astyrrean · Post by **Astyrrean** » Sat, 16. Nov 13, 05:46

Game is hard-locking at QFHD (3840x2160) on my GTX 690.

Works fine (albeit really slow at 25 FPS) at regular FHD (1920x1080).

I've seen these hard locks before - in Skyrim when VRAM usage goes above the 2GB-per-GPU limit of the GTX 690.

Is there a way to limit VRAM usage (e.g. as in Rome 2: Total War) so that I can play at my display's native resolution?

Best,

Astyrrean

Can you post a [url=http://www.egosoft.com/support/faq/faq_answer_en.php?answer=610&version=8][b]DX[/b][b]D[/b]iag[/url] report so we can see more details? I don't think any of our testers have quite such a high resolution, so we might also need to get back to you to try possible solutions, as and when we get a chance to investigate this.

I got it to work at 0xAA. Anything above that at 3840x2160 will crash the game upon launch, specifically hard lock my machine (Skyrim in high res texture mode does the same... so easily reproduced). X3:AP does the same too.

DXDiag here. More general info here:

Edit: Performance remains utterly unplayable, even at 1920x1080.
