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

[TeeEmCee]

Fixed in r8119 a couple months ago. Was caused by gfx_directx scanning for joysticks continually after a device was lost (only happened is a joystick was plugged in).

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:

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.
