I recently got a new monitor with 2560 x 1440 resolution and the game runs a little bit choppy. It also lags behind when I spec games and takes a longer time than normal to catch up if I spec a game late. For example if I put the res lower it will catch up much quicker.

I had a 2560 x 1080 monitor for some time without any issues and I've seen others usng this res, so I'm struggling to figure out what's wrong.

I've tried all sorts of settings on the voobly client already and it doesn't seem to make much of a difference.

UPDATE - well disabling 'start in window mode' seems to have helped..
