Guild Wars 2
Once again, the move to Windows 7 doesn't affect the Radeon HD 7950's performance much at all. In fact, as with our Borderlands 2 test session, the 7950 looks to perform a little better in Win8, if anything.
Since the Radeon's frame time plots show lots of latency spikes in this test scenario, here's a small chunk of the test run, so we can see the problem up close.
Again, one or two bumps in the road like this wouldn't be anything to worry about, but when those blips are everywhere, they begin to matter. Subjectively, the Radeon's performance doesn't feel horrible, but if you were play back to back versus the GeForce, you'd end up picking the GTX 660 Ti as the better option.
