[Ohrrpgce] [ohrrpgce:bugs] #2006 Starts running very slowly after alt-tabbing away

[Bob the Hamster]

Got another report of this slowness today from thorbrian, testing with the latest nightly on windows (gfx_directx):

Could this be a bug with joystick/gamerpad support in gfx_directx?

Ichiro also reported the same problem affecting all games, but I'll have to look up what he said on SS and IRC (apparently wasn't put on bugzilla).


I asked for more information and got the following response:

>Task manager reports the process going from 0-2% CPU usage when running normally to 5-10% when running at 1-2 frames per second. Also, here's the gdebug.

None of the "debug_if_slow" calls I put in allmodex.bas around nearly all calls to the graphics backend triggered, which is quite surprising.
