Summary​

Constant crashes: Failed creating pixel buffer

Description​

Opening various 3D scenes causes the game to crash.
Steps taken to resolve the issue:
- Switched to Vulkan.
- Updated GPU drivers.
- Switched back to DX11.
- Monitored GPU and CPU temperatures, GPU utilisation. GPU temperature peaked at 47C. Memory utilization peaked at ~12GB/24GB.

My hardware is an Intel i9-10980 CPU with 32 GB RAM and an Nvidia 4090 GPU with 24 GB RAM. All the game settings are maxed out. I strongly doubt it's a hardware issue, as other, more demanding games work fine.

Relevant lines from error.log:
[00:15:07][illustrations.cpp:63]: No valid environment found for illustration 'main_menu_background'
[00:15:18][illustrations.cpp:63]: No valid environment found for illustration 'main_menu_background'

The D3D line says that there are insufficient memory resources to complete the operation.

Steps to reproduce​

I'm not sure this is 100% reproducible, but twice in a row, I loaded the game, went to barbershop, then to my court, then back to barbershop, which caused a crash. This test was after 10 days of frequent crashes associated with opening the barbershop.

Still crashing in 1.10.2. Six times today! Still no crashes in any other game, in like the half year this thread has sat here.
Come on, Paradox. This is the most save/loading I've had to do since Realm Duress was a thing.

Probably not. I've never tried the game on anything besides Windows. The game also never crashes on "main" (map with UI) screen, or 2D screens (character browser, dynasty tree, character focus, all those). The crashes are always during the opening of 3D scenes, like court or barbershop (or maybe the "new" hunting/tourney event windows). I particularly notice it with the barbershop, as I like to switch people's hats around. It feels like some kind of resource leak, as I can open those scenes once or twice per session before a crash occurs. But it's not as simple as just VRAM, since the game doesn't max that out.

Some uncommon features of my setup that could be relevant:

• Two monitors, both 4K, one is HDR, the other is not. The HDR one is usually off.
• The CPU and GPU were swapped this year. Neither CK3 nor Windows were reinstalled.
• Windows swapfile either set to minimum or disabled.

Fixed by clean reinstall. Game was installed the day it came out, and was patched (and beta-patched back) numerous times.
