Horrible refresh rate and anti aliasing!!

[TaylorHoodCC]

Hey, I'm using win 32 bit SP3 XP and 1680x1050 res with a nvidia 9600gt. I've always experience extreme refresh rate problems in many 3D apps as I'm a 3D artist but within the UDK, lets just say, my screen pretty much tears in half -.-
Any ideas?

Just the usual, upgrade your drivers, BIOS (for all your hardware). Do you have problems when you run UT3? Or UDK in game mode?

: ( I've updated my drivers fully :(
I know that is usually the thing that fixes problems but in this case I have got the latest driver. Well, I can run games alright but I mean, it's the weird stuff thats happening inside 3D viewports in all of my applications.

I also have issues, for example when there is an animated texture it gets animated in viewport only when I move mouse around and yet it animates properly on hovering mouse above thumbnail in asset manager... weird. I'll reinstall my OS in the next couple of weeks anyways for other reasons (7!) so I'll see if this problem persists or what.

I have the same problem with 9800GTX + GTX260 in SLi and Vista x64
I'm only can play in 1024*768 but the quality is poor very poor.
I can't activate the Directx10 in the .ini because the screen refresh is too bad and the fps goes to 20 ....

This isn't normal ................. Any solutions??

About the animated in game things only animating sometimes..

I get that too. Sometimes it just keeps on animating. But other times it pauses unless I am moving the camera/mouse/object around. It really doesn't bother me, I don't see a real problem with it. Switching the "real time" button on or off sometimes fixes it, as does using/not using the "game mode" view.

It sounds to me like these people need to turn real time mode on in the viewport in UDK editor. I noticed the DX10 problem today in-game... lol I was getting like 1 frame per second. When I went back to DX9 it went back to normal. My only issue I'm trying to figure out a workaround for is that I can't get antialiasing to work with UDK. I've tried the nvidia UT3 profile, with my udk.exe renamed to ut3.exe - didn't do squat.

Ok I used nhancer and combined supersample with multisampling gives me decent AA... but at a heavy cost.. and I mean heavy. Goes down to like 9 fps at 1680x1050.

Are you in the editor? If so, there is a realtime button for each viewport. This is a performance optimization when working in the editor. If this doesn't fix your problem, elaborate a little more and I'll see if I can't help you further.

@Crzyhomer RT did the trick, I was in the material editor! yaay

Thanks

Hmm, after reading above posts and using realtime button or not, my frame rate is still awful in editor only, not in game. I have win 7 64 bit, ati crossfired 4850, e8500 at 4 ghz, 8 gb ram memory and everything flies away except udk editor. UDK or UT game in full screen or windows at 1680x1050 runs at 100+ frame rates, but editor as empty on load 12 and with map content poor 3 fps. It seems that editor it self doesn't use any gpu processing.
My cpu is almost 95 % busy on both cores when editor runs.
Please resolve this, otherwise there is no point of UDK for me.
For example Unity 3d editor and Crytek 2 are using 20% of cpu power and flies with 100+ fps no matter how overcrowded with content they are.
