I'm playing with Aero disabled on a modern Windows OS, build 7052. Is there any reason why one API would have more input lag in Dolphin? Also, are there any other reasons to use one over the other?
I ask because I generally tend to assume OpenGL is better with emulators, but it seems DirectX11 performs better in Dolphin, if only slightly. I'm not sure if this was always the case, but I do know my AMD card recently had a ~70% improvement in CPU overhead with DX11 with the latest driver update.
The only difference is that OpenGL becomes a stuttering mess in some scenarios with texture cache set to the middle for certain games, while DX11 is perfectly happy at the "Safe" setting. My other graphics settings are: 1080p fullscreen, auto internal res (3x), no AA, 16x AF, scaled EFB, Per-Pixel Lighting, and then in "Hacks" I've only got "Store EFB Copies to Texture Only", and XFB set to "Virtual". Everything else there is disabled (apart from the texture cache setting for OpenGL obviously).
