First of all, Nestopia was pretty consistently 1 frame quicker than FCEUmm. There are a few conclusions we can draw from these tests. Enabling it had no effect on performance. Ubuntu 15.10 + RetroArch 1.3.3 in KMS modeĬomments: video_hard_sync was left off. Having this feature enabled has been reported to add input lag, but I didn't really investigate it. I filmed while jumping repeatedly (approximately 30 times for each test) and then analyzed the film clips frame by frame to get the average input lag.Ĭomments: Nestopia was pretty consistently 1 frame quicker than FCEUmm.īsnes-mercury-balanced: 6 (often 5) framesĬomments: Xbox Game DVR feature was disabled in Windows' Xbox application. I filmed the monitor and gamepad with a Canon EOS 70D in 1280x720 mode at 60 FPS. each platform's default setting was used.

No changes to the input driver settings were made, i.e. OpenGL graphics driver (which is the default setting) was used for all tests on all platforms. I tested input lag in NES and SNES emulators and used the following two games: Gamepad (used for all tests): CIRKA USB SNES replica This monitor supposedly has almost no input lag (~1 ms), but I've only seen one test and I haven't been able to verify this myself. Monitor (used for all tests): HP Z24i LCD monitor with 1920x1200 resolution.
This topic may be old and tired, but after googling extensively, I couldn't really find much hard info and test results (but I did find a decent amount of subjective opinions). So, I set out comparing RetroPie on the Raspberry Pi 3 to RetroArch on the PC (both Windows and Linux), to see whether there are any significant platform differences. The games simply seemed much harder to control than I could remember. After playing a lot of old NES/SNES games on my Raspberry Pi 2 (and 3) using RetroPie, I got interested in investigating how much input lag there is in the system.
