So far everything is awesome. Went from a Nvidia Geforce 8800 GTS to an Nvidia GeForce 9800 GTX+ and am having amazing results. BUT there is a problem. I can play all of my games now at max settings at 1680 x 1050 resolution, but on a few graphically intense games (Oblivion and Fallout 3) I am noticing a ton of texture pop. (Detailed textures suddenly springing up not too far from you.) I have all the fade settings at max distance, (tree fade, grass fade, tree LOD, etc.) I have no stuttering and a great frame rate actually, but large blooming trees will suddenly change textures and new foliage will pop up in them as I walk toward them. Could this be my CPU bottlenecking the cards performance or something? Or maybe my RAM? I have intel core 2 quad at 2.4g and 2GB PC6400 800 mh RAM. Could this cause a problem with texture loading?
I downloaded the latest drivers for my card from Nvidia when I installed it. Also their automatic driver search tells me I'm up to date. I did get a message in SiSoftware Sandra Lite telling me that my driver BIOS was more than 3 years old, but I dismissed it as nonsense because I had JUST downloaded the newest drivers on the site. And I downloaded my motherboard's latest BIOS a few weeks ago. So I have no idea what they are talking about.
Have you tried tinkering with the 'Manage 3D settings' in the NIVDIA control panel. I suppose it could be the actual game them selves that are the cause? And not the Graphics card.
