So, I've tweaked and tweaked, and I've Oblivion running quite well, despite my terrible hardware. But, there is one thing: during fights, or whenever I am dealt damage, a blur effect, or something, goes over the screen. Whenever this happens, my computer bogs down terribly, and I'm stuck with about 4 FPS for several seconds afterword. Every time I am hit this happens. This, as you might imagine, makes combat very frustrating. So, I'm wondering if there's something, in the .ini file perhaps, that I can edit in order to stop this blur effect from happening. If anyone has any advice, I'd greatly appreciate the help.
My specs are here, if they are relevant to my problem:
AMD Athlon XP 2500+, at 1.83 Ghz 512 Mb PC3200 RAM GeForce FX5600 Ultra 256 Mb
Thanks in advance,
