I don't use VR myself (yet), but I've heard you need a 980 or better for DK2, at least with Horizons.
Thing is I see plenty of people describing gameplay with a 970 as "silky smooth", find it hard to believe a 970 wont run elite on DK2 even on lowest settings.
I have 6 cores at 3.8 and 8gb of ram which should be plenty. Zero change from the upgrade just seems a bit fishy when all my benchmarking software is giving a 50% framerate increase.
You could be experiencing a bottleneck, you may want to run some tests to see if its your cpu is holding you back, a good rule of thumb is keeping an eye on cpu/gpu usage, if your gpu usage is low but cpu usage is high then cpu is causing the slowdown, if cpu usage is low and gpu usage is high, things are most likely alright.Well... just like the title says really! I might wipe my PC and start over as this seems a bit off.
GTX 680 benchmarked at 80fps max
GTX 970 benchmarked at 120+ fps
Both judder at a little under 75fps in ED with all settings at Low. Absolutely no improvement from the new card.
What gives?
Here is a decent review of the 970 have a look at some of the benchmarks as they still include the 680 results as a comparison
