I have my graphics set appropriately for my system, that's all. I don't ask for more than my system can offer. I'm seldom, if ever, below 90 fps outside of a station. Inside it drops below 90, and pretty much stays there, that's fine with me. I really don't care about how it "looks/performs" inside/around a station, I want it fluid where it counts, outside, in combat. So, no Dash, ASW disabled, and old drivers.
I've tried endless combinations of drivers, Dash, and ASW until I'm blue in the face, and they all induce stuttering to some degree, so I've found a combination that works great at my end.
To be honest, I find Dash to be the biggest culprit contributing to stuttering, or overall poor performance. With it off, Ed runs much better. I just simply don't like the artifacts of using ASW, it looks horrible, so it gets removed/disabled as well.
I thought CORE 2.0 and as such Dash were now (or very soon to be) the main branch of the Oculus runtime? If you have Dash disabled at present I wouldn't expect it to stay that way for more than a few days or weeks at most....
