The RetroArch menu runs fine. My refresh rate is good and I stay at a solid 60 FPS. However, when I start any core, the FPS drop to the 50-56 range. My estimated screen framerate drops to ~52 Hz with over 100% standard deviation. I have an overclocked i7700k, so I shouldn’t have any issues running gambatte at full speed. Hard GPU Sync, threaded video, and switching video drivers all have no effect. This occurs with the latest nightly and latest stable release. I’ve already tried a fresh install and re-adding my custom settings. Any idea what would cause this?
