Max resolution for Unreal Editor 2k4?

[unbecoming]

I recently changed over to my lcd's native resolution since there's many scaling issues with the lastest cards out it seems.

After changing to 1920x1200 from 1280x1024 (where UED ran fine) UED now it is choppy like I'm getting 10 fps or something.Just trying to see if anyone has this problem or in fact there is a max res for UED;Drivers perhaps?

I'd rather not change resolutions per application or game if possible.

Thanks for your help.

Define "choppy". Of course a larger resolution lowers the general framerate. This affects realtime preview and also the update rate when moving the camera or any map objects.

I turned off real time and dynamic light as it normally moves smoother when those are off,but to my surprise it acted the same under those conditions as well.I have 4 gigs of ram,good card,and CPU. :(

I can actually see the screen redrawing itself,like some kinda refresh issue.It does not act like this in game.I get high smooth frames even at higher resolutions.Vsync always off.

At 1280 res (previous settings) with a 75 refresh UED ran fine.Now that I am at 1900 with a 60 refresh I actually see the screen redrawing itself every single time I move one UU.I normally keep my UT res the same as my monitor.Keep in mind this map just had about 50 brushes at the time with no meshes or anything else.It's only in alpha stage.

Too many problems with drivers and scaling.I truly think they are the cause of all of the recent problems I've had.I think I am going back to an older card (driver) where everything scaled correctly and ran fine in UED and UT.

Thanks for the input.
