When I restore a saved game, or leave a current game and
come back, my framerate is severely degraded, like
33-50%.  It stays degraded as long as I'm in the game,
or until I do something that causes renderers to re-initialize,
e.g. changing resolution.  This means that everytime I die,
or even just go to 'options' to check my settings,
I must do the following:  go to options, change my res to something
other than current (which will always be a res I don't want), get back
into the game, then immediately
go back to options, change res to value I want, then go back into the
game and reload my saved game.  Or, whenever I die, I must
get out of the game completely and then relaunch.

I'm using a 1900 xt, 6.5 drivers.  If I plug in my
old nvidia 6800 GT, I don't have this problem.
Anyone have/not have this problem?
Is there a simple one step way of re-initializing the
renderers, like a console command?

I don't have this prob on any other game except fear, both the demo
and retail game do this.
