[Duplicate] Graphic betting bugs using Vulkan

[Kamil]

I noticed one interesting thing related to graphical bugs with Vulkan in GZDoom
When Precache GL Textures and Sort Draw Lists by Texture are turned on, graphic bugs appear in Vulkan mode

Could you please be more specific? What's you graphics hardware? What was the map you were playing? Posting a screenshot would help too.

[Kamil]

Yes, I can tell you what equipment

I was asking about a screenshot of visual issues, not of GZDoom console.

[Kamil]

I understand you. But you also asked about my equipment. I provided a screenshot. But I will also show you a screenshot with my problem.

If precaching “helps” to reproduce the issue quicker, it can be out-of-memory case. Usually, it just freezes.
Is this GTX 750 Ti with 2 GB of VRAM? In fact, even with 4 GB it’s quite easy to exhaust it if texture upscaling is used.

Since this seems to a recurring issue with vulkan, maybe we need to implement our own limits now that the current implementations apparently do not gracefully handle out of memory situations.
