Using touchpad as mousewheel makes the game unresponsive

[phobos2077]

If UseScrollWheel is enabled and trying to scroll the main view using a touch pad on my laptop, the game becomes unresponsive:

• Key presses register with a big delay or not at all
• Mouse cursor (hex mode) seems to flicker in an unusual way

My guess: because normal mouse wheel event only happens once in a while, it works normally. But with touch pad you're supposed to scroll very smoothly, so an event fires a hundred times per second probably, and whatever code is responsible for processing the event, takes too much time to do it.

OS: Windows 11
Sfall: 4.3.6 (from Et Tu 1.8 release)
Hi-Res patch is disabled

Weirdly enough, disabling "Smart VSync" in Intel Graphics panel seems to have fixed this issue. Seems to be related to how any kind of external FPS limiters breaking the game.

Closed because the cause for the title issue is found and solved (external FPS limiters).
The further discussion about FPS should continue in #322.
