Obtaining the full screen dimensions via SDL_GetCurrentDisplayMode, Raspbian on my RPi3B is running at 1920x1080 @ 60 Hz. The pixel format is 370546692 (SDL_PIXELFORMAT_RGB888).

I expect that could easily explain the performance difference compared with mine, it's asking a lot of the RPi's GPU to drive a 'full HD' 1080p display. Having said that, the 38 fps you are getting is not that much worse than the 50 fps I am getting in absolute terms. Of course the jerkiness arising from it not managing to keep up with display refresh makes a big difference subjectively, but that's what graphics programming is all about!
