Emulator Issues #5904
Text in Render window actually slows emulation
What went wrong?
Displaying FPS or 'Show Statistics' slows dolphin. In OpenGL
What did you expect to happen?
It shouldn't impact performance
What steps will reproduce the problem?
Load a game, then tick 'Show FPS' or 'Show Statistics' (statistics slowdowns more)
64bit dolphin 3.5-257
Did the game ever work correctly?
i don't know if this is related but when the font was yellow there was no slowdown...
Operating System and version:
Ubuntu Linux 12.10
Any other relevant information:
intel hd graphics (intel core i3-330m)

the actual rasterfont implementation is outdated as hell. so maybe your gpu/driver doesn't support to do this in hardware.
it should be fixed in immediate-revmoval branch. there also is the yellow font issue :-)
this branch is merged in glsl-master to reach core compatibility

I don't know crap about graphics coding, but I took a peek at the code for the FPS display, and it just looked plain slow.
Maybe the compiler optimizes it heavily, but this issue could be valid, though I always play with Show FPS on anyway. Since I never turn it off, I don't have numbers.
