Glad to hear you got it working. I haven’t made any attempts to get better performance yet. I do notice that it appears to be running in a high resolution when I look at the text in yellow at the bottom left. Maybe just running at a lower resolution using the runcommand dialog box that comes up before a game starts would be enough. I’ll give it a shot.
