Ok so... my new pc got here yesterday. Yes, it's Vista. Yes, it has an nVidia card. However, I don't think the problem is unrelated (or if it is, it's not the types discussed in the sticky).
Quadcore 2.4, 2GB, 512 GeForece 8600GT. No errors or bugs after installing my misc stuff and removing the damn yahoo toolbar and default search embedded in 20 places.
I downloaded and installed the latest drivers. Downloaded and installed the vista POL from site. Installed the XIness and whatnot.
Ran POL with it all done. Grainy view. You know, with the text all garbled and barely legible. On my last PC (XP pro sp1) if this happened it was usually if xi crashed randomly... restart pc and reinstall drivers and no issues. That didn't work this time. The XI rendering looks okay, avatars and text (log, names) look like I'm on a PS2. Rescaling the window makes it look even more comical. Both the POL viewer and XI have this same problem. This is with all the default graphical settings and not using Windower.
This would all lead me to believe it's a driver issue... so I downloaded the beta drivers, fail. Downloaded old drivers, fail. I'm really starting to wtf now.
...So I download the official benchmark program. Really was quite adorable with all the tarus in bst rse and all. Ran low resolution first. Ran 60fps for most. Ran high resolution, did about 30-40. A little choppy. Oh well. That's a freaking ton of tarus.
...Ran the 'demonstration' option on high resolution. Holy crap, ran 59fps flat the entire time, simply gorgeous. I was not aware that xi could look that good. I was shocked. I am now confused as hell, as a result.
How can the benchmark demonstration run flawlessly on highres uninterrupted framerate but POL/XI proper look like my PS2 version? This is why I say this is different than the sticky since apparently things -can- work beautifully. Everything else on the pc is perfect. I've reinstalled the POL viewer, drivers, whatever and no help. I have no clue what's wrong.
Edit: I've managed to make things look mostly playable... on xi windowed mode and low resolutions. It's still absolutely nothing like what the benchmark demo did. Also, I hadn't considered that stretching the POL window might not even be possible to correct in vista because of the stupid opaque borders. ...Toying with additional settings in the xi config to max out quality also helped a little. Still lousy framerates @ whitegate mh and ah.
So issues still:
--Window resizing (well, I'm used to having that at least) and particularly the look of text with it.
--Maxed out settings still not close to the benchmark program output.
--Windower doesn't work [but I know that not 100% with vista].
I'm considering installing the beta vista SP1... I read on another forum that it helped someone with a 8500GT.
