Just got a 1080p monitor so I thought I'd try to record something to test the quality. Here's one of the best games I've played. Still looks great. Plays great. Is great. Better than Crysis series.
Using Dolphin 3.5-367 64bit. Notable settings are: Direct3D11. Aspect Ratio Forced 16:9. Internal Resolution 3x Native. Anisotropic Filtering 16x. Widescreen Hack (I don't think it matters). Frame rate chugs when recording but that's expected. Runs smooth when just playing, minus a few fps drops when loading an area.
