Oblivion and SoftTH
Oblivion is a very large RPG, with an expansive world, and numerous play options.
Framerates with a GeForce 7900GS primary and a Geforce 7300 Secondary were decent. Best results were achieved with the resolution set to 3072x768. 3840x1024 worked ok, but was a bit more jerky
Setup Instructions
Setting up SoftTH with Oblivion is quite simple.
All you need to do is copy the d3d8.dll, d3d9.dll, and softh.cfg files to the Oblivion directory. Then, load up the Oblivion launcher. Pick options, and select the resolution that you want from the drop down box.
Didn't notice any major problems with running Oblivion, other than some sluggishness outdoors.
