Well, I tried 355 driver, not .98 version, but a bit earlier verion. It did not change anything. Keep in mind I was on even earlier driver (from Feb 2015) for almost a year without any issues. I played on this driver on Sunday last time and on Tuesday after the maintenance it started to flicker. So, reverting to earlier than the current driver would not help at all.
I am on WIndows 7 Pro 64bit at the moment, DX11 with DX9c installed as well. I did find that solution you quoted and made all 3 items run in WinXP SP3 compatibility mode, it greatly increased my FPS (by around 20-30), but it did not help with the texture objects flying all around my screen with high frequency.
Ok, this I have not tried and I will in a moment, and report back. Thanks anyways.
