Did you set \r_vbo to 0?

r_vbo is/was 0. It seems I have to move to cause the crash. Crash happens randomly as it seems (depending on where to move, and at what time?). Sometimes this map crashes after moving just a few units, sometimes it doesn't crash even after minutes.
EDIT: Happend again right now, after I changed some cvars and did a vid_restart. I changed r_vbo, r_swapinterval, r_picmip from 0 to 1 and vice versa. It seems as if a vid_restart will more likely cause the crash. Do you think a vid_restart could cause the crash?

In vulkan you should manually preallocate geometry buffers before use so overflow may happen on such big maps, \use r_vbo 1 to fix that, it will also increase FPS

Okay thanks for the info!
Suggestion: what if #ifdef/#else the cvar somehow? I assume non-developers don't know to start with r_vbo 1.
Btw, vulkan seems really fast, you did a great job here!

No need in #ifdefs, corresponding code is already there.
Also it is a good idea to enable vbo in vulkan by default.
So I consider that issue is resolved now.
