Provide extra information to complete the original description of the issue:
I have LG C1 120hz. When my mouse inside msfs2020 window and clicks to anywhere within window, my fps drops to 60, even with Vsync off. When i alttab to click out of msfs2020 window, my fps goes back to 120fps as it should be. Latest nvidia driver released 566.14 , clean install, only unlimited shader cache selected on nvidia control panel, nothing else altered. All shader caches cleaned. Tested both windowed and fullscreen, same result. 7800x3D rtx4070 win11 23h2 2x16gb. Previously Nvidia Reflex was causing same issue when On or On+Boost. Now even it is off and no vsync it is still happening. Now it is switching between 120 and 60fps.
