Hi Guys,
So, I get a delay where the screen goes black when I alt+tab between SC2 and any other windows app which I thought was normal and wasn't bothered about however last night I watched LiquidTylers stream for 10-15 mins and noticed him alt-tabbing between sc2 and switching music/checking forums then going back to SC2 with absolutely no lag time whatsoever.
Anyone know what could be causing the 15 second delay on mine? PC is:
Intel Quad 6700 @2.66ghz
8gb DDR2 Ram
ATI Radeon XFX 4890 (1gb DDR5)
possibly display drivers?
Any feedback appreciated.

Switch to windowed fullscreen mode. You're probably running in fullscreen, which is BAD for alt+tabbing.
Edit: Display drivers? If they're not up-to-date, go update them now please!

Do you play in Fullscreen mode? If you do, then change it to Windowed (fullscreen)

But in windowed full screen the game will take the color of your desktop and u will expirience FPS drop
|
2GRe-Play-, you're thinking of windowed mode. In windowed fullscreen, there will be no "taking the color of your desktop" because windowed fullscreen eliminates the windowed border.
Yes, there will be an FPS drop and that's to be expected. I am an alt+tab-oholic and run all my games in windowed fullscreen (also due to the fact that I have multiple monitors) and I never have framerate issues. If there are framerate issues, try closing other programs, etc...
There are drawbacks, but that's how LiquidTyler achieves lag free alt+tabbing.

It's a known problem with ATI cards. They handle fullscreen badly. As has been mentioned, playing in windowed fullscreen (no annoying bars) eliminates the problem. There is a small hit in performance, but you wont notice at all, unless of course you're running at the limit of whats possible with your system already

That did the trick thanks a lot guys

I find this incredibly hard to believe.

Beaten to it, I can't stand games that don't do well in windowed fullscreen, I'm ADD enough to want to have something going on my second monitor while I play.
I think I've had 2 games and 2 livestreams going at once at one point (Destiny+bluetea's 2v2s, a slow moving SC2 custom game, and the Rift Beta)

Don't, ATI drivers are terrible.

It's your processor.
It used to take me 45-60 seconds (YEAH, A MINUTE!) to tab between windows at Starcraft 2 with my old AMD 2400+ dual core. With my new i5-2500k, it takes like 2 seconds.

Looking forward to change your Motherboard, are we? (Intel-Chipset bug)

Meh, I can get a free upgrade to a Z68 chip or I can just chill with my SATA 3 ports and (my currently functioning) SATA 2 ports.
Plus, it gives me an opportunity to change my ungodly large heatsink should I choose to do so. :D I'm also super <3'ing quad core 4.5 Ghz processing speed.
So uh...yeah. :D

I can alt tab (I usually use the windows button, though) really fast on my laptop, I just looked and I'm using Fullscreen (NOT windowed). I have a core 2 duo 2.4 ghz with an nvidia 8600M, 4GB DDR2 RAM, hardly a powerhouse, but alt tabbing takes maybe 2 seconds. I have a second monitor that I like to tab out to change pandora or whatever on. It could very well be your drivers.

Wow, bitter much? Changing the mobo is hardly a big deal.
Edit: I have DDR2 RAM, 4GB

I don't think it's your video card or processor. You're still using DDR2 ram, which is bottlenecking your computer's performance.
The specs on my laptop are worse than yours in every regard, except that I have DDR3 ram. It takes me about 2 seconds to alt tab out of SC2.

I have the same problem. I have a ATI 4870 X2 and I just updated the drivers a few days ago. They didn't fix it. For me, it usually takes 3-5 seconds to maximize when I first start starcraft, but the longer I have it open, the longer it takes to maximize (sometimes upwards of 30-45 seconds). I have a Phenom II X4 3.00 Ghz quad core.
My friend has a newer ATI card (5800 or 6800 or something) and apparently doesn't have alt-tab issues, so maybe it's only the older ATI cards. It's so frustrating though, it's embarrassing that this problem hasn't been fixed for a year now...

On one of my computers, an upgrade from a Core i5 to an i7 made it better.
On my brothers' computer, an upgrade from 4 GB to 8 GB of RAM made it better.
On another one of my computers, an update in drivers made it better.
So pretty much, it depends on a lot of factors. Since you have 8 GB of RAM, a good card, and decent video card, I'm thinking it's your HDD and/or drivers.

To fix this problem change your desktop resolution to the same resolution as sc2. This is what I did to fix it.
|
i dont know why there a bunch of posts in this thread... quit simple, choose windowed full screen option in the options menu, bam! lagless alt-tabbing.
|
The problem is simple. Like I said previously, it's a problem with ATI cards, not weak processors, hard drives, lack of ram, type of ram etc. I have the exact same problem, and I dont exactly have a weak PC
+ Show Spoiler +i7 960 @ 4.2 ghz
12gb g skill ripjaw 1800 mhz
Asus P6X58D Premium
vertex 2 ssd (where starcraft is installed)
sapphire 4gb 5970 toxic @ 950mhz
(i used to run the same sytstem in trifire with a 2gb 5870 toxic, and still got the alt tab lag)
The solution is also simple. Run the game in windowed full screen. If you do you'll see there is no more delay, alt tabbing is instantaneous. Also if it were a hardware issue (as in weak components), the windowed fullscreen fix wouldnt work, because running in fullscreen is less stressful than windowed fullscreen.
|
You have an i7 960?!?!?! O.o
Also, I have an ATI Radeon 5770 and only had that problem with my old processor, for another data point.
|
Everyone keeps saying windowed screen fixes this. Yes, that's true. But I've also found it more difficult to play in windowed mode since scrolling around is a little more cumbersome and slower (I run multiple monitors). If you only have one monitor, this may not be a big deal, but windowed mode isn't the only way to fix this.

Hi Guys,
As quite a few people have already mentioned the fix for this was definitely switch to windowed full screen. SC2 minimizes and maximises like you're just alt tabbing between 2 IE windows.
I know a nice shiny new i7 CPU would improve ingame performance but honestly, I play the game at 1921x1200 at Ultra Settings and don't get any stuttering aside from when you've got something like mothership + 600 units on screen so until I NEED to upgrade this'll do me.
For anyone who is having this problem just do as already mentioned and switch to windowed full screen
|
Sorry Jacosah, just noticed your post.
I have a dual monitor setup as well, get absolutely no problems scrolling around....
|
I have an old ATI card (HD 4850) and for me the alttabbing time improved significantly when I ran fullscreen starcraft at the same resolution i have my desktop

I also have an ATI card, with the latest drivers, and alt+tab out of SC2 with no problem.
I really think it's the ram, because even on my machine with a 9600gt still had problem's alt+tabbing, and it was also using DDR2 ram.

In his case how can it be the ram? Running in windowed fullscreen is more stressful than regular fullscreen. So if it was a problem with weak ram, the fix wouldn't work.
Also I have 12gb of 1800mhz ddr3 ram. And I get the same problem. Is it because my ram is weak.

Ladies, gentlemen and liquidians.
Problem has now been resolved, can't we all just get along now?

If you have more than one screen, how do you avoid moving your mouse outside of your gamescreen, and onto your other screen? This happens to me all the time. I have my settings exactly so that I can just fling my mouse to the side to scroll around, but in windowed screen, I have to pay attention to where my mouse actually is. Might just be laziness, but I don't see any reason to have to pay attention to something like this when I can play in fullscreen. Anyone else notice this in windowed screen?
|
Jacosjah, I think your problem is that you're running in windowed mode. If you go to the graphics settings there another option called "Windowed (Full Screen)" instead of plain ol' "Windowed". If you switch to that it'll work fine .
|
I don't like the windowed full screen fix because my fps drops by about 10-15.

This is just wrong. I also have this problem and i'm of course running SC2 at the same resolution as my desk. ATI drivers are just fucked up and i don't want to play in Windowed Fullscreen because my comp is already somewhat older and i don't want to throw away FPS just because ATI is to dumb to fix their drivers.
|
fullscreen windowed works fine despite losing a few fps, but it screwed me coz Im used to set the gamma at 90% of the maximum value in the game, and fullscreen windowed uses the desktop gamma, that is fine for desktop but horrible to sc2, i cant see shit. Tips?
