I have updated to BETA 3 and 0.4.3 version of Oculus Runtime, and now I'm experiencing strange graphical glitches playing on my DK2: instead of black color I see reddish tint, plus vertical screen tearings here and there. Overall performance is good, however this graphical issues looks ugly... Prior to 0.4.3 everything was OK.
I'm running GTX 970 SLI, i7-950, 12 GB, Windows 7 64-bit. Latest (vanilla) nVidia drivers. Other games and demos I have tried runs and looks OK, so this is Elite: Dangerous specific issues. Also, I have tried capturing screenshots, and everything is OK on them, so this is something to be with Oculus Runtime, I believe... Any suggestions?
Thanks!
UPDATE: I just have traced problem to SLI. With disabled SLI everything look normal. Also, my single Asus STRIX 970 GTX is able to run maxed out Elite with 70 FPS on Rift (SSAA is 1.5 in settings.xml). While SLI setup showing roughly 75 FPS with 95% load on BOTH GPUs... And those graphical glitches
UPDATE2: This was my faulty SLI connector... Fiddled with it a bit, and everything now works fine. However, my 2x970 SLI setup cannot run 4K Elite on Rift with 75 FPS...

Max what I'm getting is ~30 FPS when <SSAA>2</SSAA> is specified in settings.xml... Any other way to make text more readable on Rift? Thanks!
