I have a Lenovo T420 with Nvidia NVS 4200M graphics, Also have an Asus PA248Q IPS screen.
The laptop have a display port and a VGA port.
Driver is the latest from Lenovo website.
I im currently using Displayport connection.
When playing a game full screen with DP/HDMI at 1024x768 I can get 60fps but every 10 seconds or so it drops to around 40fps for 2-15 seconds or longer.
where if i hook via VGA playing same game at same settings i can get 60fps stable.
(this game is not demanding at all on both CPU and GPU )
However if i window mode (desktop is using 1920x1080 with game running at 1024x768 windowed) both connection will get 60fps stable.
Any idea why it's doing this? I'm skeptical with running my 1080p screen with a VGA cable so I'd like it to go with HDMI or DP.
