pommefritz: I successfully ran Omikron once, but had no sound. I managed to change the resolution in-game as well to 1920x1080 which is my TV's resolution.
However, the second time I tried to run it (both times using Galaxy), I got the "not enough video card memory" error. I also tried running the game not using GOG Galaxy and when I do that, runtime.exe crashes and I can't load it.
Since I did load the game once, but was going to look on the forums about sound issues and then couldn't run it a second time, I'm stumped as to how I might fix this.
I'm running Windows 10 with a GTX 970 so I can't imagine I really don't have enough VRAM here.
Thanks for any suggestions you might have, either about running it or the game lacking sound once it does load. In "settings" I do have a drop-down menu for resolution choice and thought lowering it might help, but the menu is blank - no resolutions available to choose.
I'm having the exact same problem. I tried running the Verify & Repair function but it had no effect. I will probably try a full reinstall if I can't figure out anything else.
