I tried 2 different hdmi and display port (which is what I usually run) cables, same results. I just re installed an older glib and ran benchmarks with both current and older libs, and posted them in a thread here about testing the new libs. Some results improved with new libs, but 3 went down significantly. I will try the old lib again, and see if fullscreen tearing stops. Only change to computer was update, and cables and monitor confirmed good.
