Mouse handling very slow since drivers > nvidia 90

hi all,

i experience a serious slowdown
in my mouse handling routine with
newer drivers from nvidia.

basically the mouse handling routine
does a GL_SELECT rendering of my widgets
followed by a GL_FEEDBACK render loop.

it used/uses to be very fast (~1ms)
on systmes using 81.xx or 87.xx drivers
but is very slow (~200-500ms) on systems using newer drivers, 90.xx or higher.

did anything special happen between these
drivers? is this in some way related
to the newer multiscreen compatibility modes


gDebugger claims that it can find software fallbacks in your code, so you might want to try it.

hmm as far as i know feedback&select render are
always done in software?!
