Hi. I have looked everywhere for answers and have come up empty handed and very confused. My original system was an Alienware with a core2 duo (2.66ghz) 2 gigs ram, and a Nvidia Gforce 7950gt. And my operating system was XP. I recently upgraded to 6 gigs ram, Nvidia GTX260, and switched to Vista (32 bit). I got Oblivion when it first came out and it's my favorite still. It ran pretty well on high settings on my old system, but i wanted to max it out. Since I upgraded, I've experienced lag in places that ran perfect with my old system, like any of the towns or the tutorial at the beginning. I have all the recent patches for my video card and Oblivion, and I've tried using the Collector's Edition along with the expansions or the Game of the Year editon. I also know that DX9 games don't work as good with Vista sometimes, but all the forums I've been to say Vista should be fine. I really am bummed out cuz I upgraded to get the most out of games like oblivion and Fallout 3. Oh yeah, Fallout 3 runs better on my new setup than Oblivion. Can you feel my frustration??? please help me. I know it has to be a simple solution like tweaking my Nvidia control panel.
my system says i have 5 gb ram (vista eats up the other gb). I already tried the anti-aliasing and everything else i could think of. Fallout 3 works like a charm on high settings with 4x anti-aliasing, and it has the same engine as oblivion. even Bioshock 2 works great. And yes i have the most recent drivers for my video card. I've also gone through my Nvidia contol panel and tweaked all the settings for oblivion, like forcing the HDR with anti-aliasing enabled. I think God knows how much I love oblivion and is punishing me. Thank you for your input. I won't give up, even if I have to go back to my old setup. I've heard that oblivion fans are switching to ATI because of compatibility issues with newer Nvidia cards. oh my ram is: 2x1gb ddr2 Patriot and 2x2gb ddr2 Corsair, all at 800 mhz. blah blah blah blah
I would suggest to looking into the power supply i know for fact that gtx260 uses upto 450-500w at it's peek. That is one main issues w/ pre-build systems is the power supply when upgrading graphic card.
