Judder on Radeon cards?
Only skimming the surface of the new SDK's Unity integration, as I don't have time to dive too deeply at the moment, but I was reading through the release notes and saw this:
I'd like to avoid having the user wonder at the cause of judder, so I'm hoping to automatically address this at runtime. It's simple to detect the GPU vendor, and even specific GPU cards if needed. Should I turn off MSAA when I detect an AMD card? Is there any reference as to which specific cards have this problem so that I can narrow this down a little bit? I assume this problem only applies for those using a DK2, right? Or am I barking up the wrong tree entirely? :)
Thanks!
* On some Radeon graphics cards, multisampling may cause scene judder.
The work wound is to turn-off multi-sampling for the back buffer.

- All turned off in the Catalyst Control Centre... still judders
- Does this judder issue appear on all radeon cards or only on certain models? And what could be the reason for this? As I just got a r9 290 this troubles me a bit. :(
- I have an R9 290X the only time I experience Judder is when the frame rate drops below 75. In the Pilot SDK the was a dx9 .dll file that was needed for Timewarp and I found that when ever I had it in the build folder I would get Judder regardless of frame rate. This may well mean that Timewarp doesn't work with AMD cards yet, try disabling it on the OVRController and make another build.
