Hi guys, I have this odd issue where mouse movement doesn't appear to be "smooth" when moving the cursor around and occasionally clicks don't register (same issue in geoscape, tactical, and menus.)

Using an original copy of the game patched to v1.2 on DOS. This is the only game i have this problem with... Any ideas?

Pentium MMX 200Mhz
128gb RAM

Game runs stupid fast due to my CPU but it's totally fine to play when I slow down the speeds in settings - tried setmul to throttle the CPU as a test but I still get the mouse issues...

Scrolling the screen in battles is fine, but general cursor movement and clicking on things is inconsistent...
