I can play BF2, CoD2, and HL2 full out, but I can't play Oblivion on 800x600/medium without glitches when I turn. I have the new nvidia drivers and new ones for my mobo; I also got coolbits 2.0. None of that helped fix the problem. I also defraged my computer because I heard that might help.....but no luck. What should I try next to fix this problem?
3.2 GHz P4 HT
2 gigs OCZ platinum memory
EVGA 7800gs sc (AGP)
75 gig hd
Chaintech SPT800 mobo
im not exactly sure but Maybe its because you are running an AGP system and there is not enough bandwidth coming out of your card to keep churning out the textures smoothly but thats the only thing i can think of try turning your agp appature size up expirement withthe bios or wait for a patch and if all else fails set the texture size down to medium and it looks great still but just at medium or try turning off HDR and try going to bloom just tweak the settings and find a sweet spot in between graphics and performance
Your video card should be adeqaute and you should have frame rates of about 30 or better in most situations.
It may be your system is not set up right or as mentioned, could be your sound card.
Should be able to eliminate the sound card isue by turning off the sound and see if the chop goes away.
If that is not the issue, try going to the games forum and download the Oblivion Tweak guides. There is a lot of good information in the tweak guide and it is very effective. I am running a homebuilt AMD XP 3000 with an ASUS A7N delux, 2 meg of ram and an ATI 1600 pro. Frame rates not the best, 20 to 35 (usually high end except in darker environments which seems backwards to me), but no chop. I also run with Anti-aliasing at 4X turned on (because I can) in conjuction with HDR.
