Lagging when using LevelEditor

[QysteiN]

Run Task Manager in the background while you edit. See what (if any) program is eating up your processor when the lag spikes occur.

Does your map contain a large number of decals? They can be pretty nasty on performance, as well as simply having a lot of objects in the viewport.


Try updating your GPU driver as well.

Edit: I actually don't see your GPU driver listed. I'm guessing you have a laptop? I just saw an A then 4 numbers so I assumed it was an ATI card haha -- I've always run nVidia. Check which card you have by going to Start > Right click on Computer > Manage > Device Manager > Display Adapter.

Anyways, I checked and it looks like probably got a GT540M in there. I got this from a review site which posted with a different processor (the computer they reviewed was a 5750G but with an i7-2630QM). If you DO have the GT540M, go to nvidia.com and update the drivers. That card also supports Optimus, so if you do have Optimus running on your computer, white-list the HPL2 applications to run with your GPU. I have an Alienware M11X, which has no Optimus so I'm always using my dedicated GPU. Either that, or search for a way to disable Optimus and always run on your dedicated card. If you're like me and are using the laptop at home 99.9% of the time then it won't matter -- Optimus (as far as I know) is only a power-saving feature.

Im closing all my programs whenever I edit. The map is not that big. Im working with my class mate and she is not getting any lags.

''Your PC currently has the latest driver installed for your GPU. No driver update is necessary at this time.''
I have NVIDIA GeForce GT 540M just to put that in here.
I have no idea what Optimus is, but I don't think I have it, I tried to search for it on my computer with no results.

''white-list the HPL2 applications to run with your GPU''
Mind explaining how to white list ?
