Hi,
On my NVidia G-Sync enabled display, the screen refresh rate is usually around 144 fps.
- When I select the Kontakt 7 application, the refresh rate consistently drops to around 20 fps. When I select another app it returns to 144 fps.
- Same issue with the Kontakt 7 VST within my DAW (Reaper 6).
- If if I disable G-Sync the problem disappears. Ditto if I move Kontakt 7 to my other, non G-Sync monitor.
- The problem didn't exist with Kontakt 6 or older versions. It worked smoothly on a G-Sync display.
This looks like a bug introduced in Kontakt 7...
