Well I took some pictures last night using Mame v0.108 and Joust, all on auto resolution (my desktop is at 800x600 in case that matters). I took a picture for each rendering method (GDI, DirectDraw, and Direct3D). Surprisingly, GDI looked the best by far and the others looked horrible by comparison. Then this morning I tried messing around with ddraw and I was able to get it much crisper by manually specifying the resolution to 640x480. I then tried Marble Madness and got totally different results (D3D with no bilinear filtering looked the best). I guess I'm going to have to experiment with the video settings for each game and find the one that looks best. I attached the pictures I took last night on auto res...from the top down they are D3D, DDraw, and GDI.
