Well Vulkan would sure be nice, but as discussed above I'm not sure it's that easy to enable - but from what I understand of the quote above, they're pretending to use GLSL 4.3 but doing something which is only available in GLSL 4.4, would there be a way to officially use GLSL 4.4 instead ? In Unity games there are -force-glcore44 and similar options to force using one or another version of OpenGL, is there anything similar here, either at runtime (better) or at build time ? Which brings a question, can you please enable Vulkan renderer, as an alternative path? The above could be a bug in Unreal Engine, so at least Vulkan could provide an alternative until it's fixed. This results in hangs and stuttering in the game when it attempts to use the program that failed to link. There is at least one attempt in the game (maybe more?) to link a vertex shader output that sets the noperspective qualifier on an output to a fragment shader input where no interpolation qualifier is set. In GLSL 4.40 this restriction was relaxed. The games shaders use GLSL 4.30 which mean interpolation qualifiers must match across shader interfaces otherwise it is a link-time error. If needed I'll do more detailed bug reports after the next patch is done, and I'll also post a more detailed review of the game once I've finished it. Else the game runs smoothly, loading times are very reasonable, and so far I'm enjoying it. the "unclickable character" bug, again mentioned on other threads and probably not Linux-specific. the "persistency" bugs that are not Linux specifics and were mentioned on other threads (ennemies respawning, grapling hook disappearing. for a few seconds after loading an area the game is slugglish, lags when I turn around (probably due to shader compilation, but couldn't it be done during the loading ?) sometimes it crashes (segfault) when loading a game, but never (so far) during gameplay ![]() a few "seperation lines", 1-pixel large, that occasionally appear on the walls/rocks/. ![]() ) and then back to normal when I move around somewhat frequent flickering of textures, objects that flash shortly with a bright color (pink, green. My setup is a Debian Sid, with a Radeon R380X and 16Gb of RAM, and I'm using GOG Linux version, with settings somewhat toward the "High" range, but not "Ultra". ![]() Since you made the title generic, I'll hijack your thread, hope you don't mind So far I've seen quite a lot of minor bugs, but nothing game-breaking.
