galileo31dos01 Posted April 22, 2019 Lately I've been trying to setup OpenGL in GZDoom to work on my laptop, and everytime I do that I get this weird buggy appearance where textures and menu words appear and disappear every single millisecond. A screenshot: This happens in the last version of the source port. Also, I tried a vintage version, I think 2.x, basically older versions of GZ and the same issue is still there. It's not the custom wad because it happens with the iwad too. Neither fullscreen or windowed mode work, nor changing the resolution, tried every setting in the configuration (OpenGL renderer) and nothing. Enemies, basically "things" don't seem to bug. Some information about my system: Spoiler It's a laptop, HP. Renderer: AMD Radeon HD 7640G RAM: 512 mb Processor: AMD A804500M APU with Radeon(tm) HD Graphics, N/A, Familiy fh, Model: 10h, Stepping: 1h OpenGL version: 4.2 Driver: 8.941.0.0 (.dll) Catalyst 8.941.4, 26-jan-12 DirectX: DirectX 9, 11.0 I guess this is enough information, let me know if something else is needed. I'm not really sure what to do, probably update the drivers but if there's a simpler solution, I'd be very grateful to know. Also, I know they are different source ports but OpenGL in GLB+ has always worked fine. 0 Share this post Link to post
Danfun64 Posted April 22, 2019 Hmm. AMD, huh? My first suggestion would be to check if your drivers can be updated by following the advice in https://forum.zdoom.org/viewtopic.php?f=50&t=57979 0 Share this post Link to post
Graf Zahl Posted April 22, 2019 That driver is ANCIENT. More importantly, it's from a time when AMD's OpenGL drivers were suffering from massive problems. There should definitely be something more recent that works better. 2 Share this post Link to post
