@mitu Built SDL 2.0.14 with

--disable-video-rpi --enable-video-kmsdrm

The FPS problem still exists with 5.4 kernel, or newer one after full SO upgrade (in this case with fkms or kms), and in this way when emulator is closed EmulationStation is frozen.

Anyway I found a solution, if VERTICAL SYNC is enabled also on emulator (I added a command line parameter for this) also Raspberry Pi v4 version is ok.

If you don't have any other idea I'll stop the investigation, I don't love VSYNC because if a user has a 50 Hz monitor all games with nominal 60 FPS framerate runs at 50 FPS.

Really appreciate your help

Extremely stoked for what could become of Retropie with new video drivers.

Also still concerned about how all our video snaps are going to be handled with KMS. I spent sooo much time on video snaps and making sure all my games have videos.

if your happy with it all the retropie configuration to run it. im not sure if retropie 4.4 supports sdl2_opengles youll need to ask someone at retropie headquarters if they support this or have and intentions too. it runs very nice on a debian x64 :)
