FPS logging
-
Is there a way to save a log file of the RetroArch FPS counter? I would like to compare the performance of certain emulator cores on different Raspberry Pi models.
I've also tried to find a Fraps-like FPS logging tool for Linux, but haven't come across any that would work on the Pi's ARM processor.

@mitaholo RetroArch has the option to show you the FPS on-screen, and if you run it with Verbose Logging (enabled from the Runcommand launch menu) it will print video/audio statistics at the end of the logfile (
/dev/shm/runcommand.log). -
@mitu
The only useful stats I get from that is the total amount of frames pushed and dropped. I guess I could log the approximate emulation start and end times with the runcommand scripts and then use that time and the amount of frames to calculate an average FPS. -
@mitaholo you can just measure the percentage of dropped frames. lower percentage = better performance. you don't need to calculate the FPS to measure the performance.
i started trying to write an automated way of doing this but gave up for now: https://github.com/dankcushions/retropie-auto-testing

Good point! I was planning to just pick a representative game or two for each system and play them for the first level or so. Maybe repat a few times per game to minimize the effect of random hiccups and player actions.
