quad cores sometimes dont work well with oblivion. you may need to set core affinity to 2 cores. Also there is a tweak guide. http://www.tweakguides.com/Oblivion_1.html pay particular attention to the multithread tweaks for the ini file.
I run Oblivion on high settings, I have no mods and i have no lag (I have GOTY edition)
PhenomX4 9955 @2.8ghz
4gigs DDR2 8500
Geforce 450 GTS (I also ran it smoothly with a 7800GT)
Might be one of your hud mods.
Turn off Grass, and lower shadows if needed. Oblivion maxed out can still put some hurt down on an older video card like the 3870, and it does not support crossfire I don't believe so the 2nd card isn't helping
Hello guys, Do you guys know what might be causing the extremely low FPS? Bone stock oblivion, other than the latest patch and some HUD mods. Here are my computer specs.
2x WD caviar black 640gb raid 0
8gb Patriot DDR2 1066
Yeah its your gfx cards take the 1 3870 out try it then and like the post above says turn off grass and shadows you will notice a difference then save up and get a newer gfx card. you could always reinstall the game too something might have gone a little screwy when you installed it...its happend before. Other than you gfx cards your system is more than capable of crushing that game
