Crash to console\desktop with high supersampling

[Potefar]

Having issues with high super sampling. Whenever render target in steam VR is above 3700x3200ish per eye, I can't load any save game. If super sample is "just above" this target, it will crash to main menu with the console window open. Increasing SS further will just make RBDoom3BFG.exe stop responding. It's the same with or without HD texture packs. It allows me to start a new game at high SS though, but will crash during the first loading screen after entering the elevator..

Everything seems ok below this SS target, but I would prefer to increase it for my Pimax 5k+ to get the image sharp enough.

Hope this issue can be fixed as this mod\game until now has been the most immersive one for me by far!

From the error log:

caught OpenGL error: GL_OUT_OF_MEMORY in file ..\RBDOOM-3-BFG-release\neo\renderer\OpenGL\gl_Image.cpp line 610 caught OpenGL error: GL_OUT_OF_MEMORY in file ..\RBDOOM-3-BFG-release\neo\renderer\OpenGL\gl_Image.cpp line 610 caught OpenGL error: GL_INVALID_VALUE in file ..\RBDOOM-3-BFG-release\neo\renderer\OpenGL\gl_Image.cpp line 365 R_StaticAlloc failed on 4194304 bytes Shutting down OpenGL subsystem

Edit:

Guess this is a limitation of the OpenGL API ? How hard would it be to add Vulkan support? https://github.com/DustinHLand/vkDOOM3/releases
