My laptop has 2 operating system.. Windows Vista 64bit and Linux Mint (ubuntu).
I have a 22 inch monitor connected to my lap.. I do not use the lap display.. just the 22 inch. I have a nvidia chip in my laptop.
in windows the editor is very sluggish... to me almost unusable... to make sure this wasn't an issue with my display... I disconnected my display and just used the lap top display and I get the same result.
What is really funny... When I load up my linux OS and run Sublime with wine... it is perfect!!!! It works great on either screen just fine.
I have tried the --opengl option in windows and it does seem a little bit snappier.. but still scrolling is jerky. but really not much difference.
Any idea on how I can fix this.. Obviously the nvidia chip with the 22 inch display can handle it... it does in linux.. hahaha.
I have never had this issue in any other editor.. and I try them all.
