My PC:
C2D 3Ghz
2x2GB DDR2 Dual Channel
1GB HIS ATI4670
Windows XP SP3

Running SC2 @ 1600x900 resolution, Set graphics to Medium..

Running smoothly @ 62FPS at the beginning of a 3v3 game..
When late game, with a lot of air units + ground units, my FPS will drop to 2-5FPS.. starts lagging then..

What do i need to upgrade to improve the performance of a 3v3 game?
I think 4v4 will be laggier on my current rig..

Upgrade your processor, faster core with higher cache MB might help

my rig as in my sig

So far unless squeeze entire screen with units (both mine and opponents', esp when carriers release interceptors) or else perfect smooth all time.

Intel Pentium 4 2.8 GHz
2.5 GB RAM
256 MB ATI RADEON 9600
Win XP Pro SP3

Display Resolution = 1680 x 1050
Set Graphics = High

Plays single player skirmish only.

wow! a classic pc!

Unlike other games, RTS game is still very much playable at 10-25fps.

how do you set FPS in the setting?

ticked the "vertical sync"? or?

my pc having some slow down during cooperative games, like 2v2 or 3v3, very noticeable when huge armies are moving, then a huge battle take place, the lag still there, but when those troops vanish, performance instantly improves, not sure what is the problem, but the starcraft tells me that im the one who lag. Dont understand why it happens, i dont think my pc is that low end compare to most of those players out there.

pc spec:
i5 650
2x2gb DDR3
2x1TB WD caviar green running in raid 0
Asus 4850 512mB GC
Windows 7 32bit(3GB ram usable)
Game graphic setting=low(seriously this is strategy game, i dont need that)
Resolution=1600x1200 or 1920x1200
Internet bandwidth=streamyx 1Mb(tested DL~1.5mb/s, UL~350mb/s)

anyone using ATi graphic card and have problem with slow tabbing in the game once u tab out?

me, with my 1GB DDR3 HIS ATI4670.
not sure if it's because of the card tho... might be caused by OS/RAM/CPU im not sure...

anyone not using ATI graphic card and experiencing the same issue?


Edit:
I also experienced PC hangs after quiting the game a few times without restarting PC..
Let's say after quiting and reentering the game more than 3 times for fb/surfing/msn etc, then when i run the SC2 icon on my desktop, it seems like SC2 is loading but the screen remains black color and CPU not processing. Ctrl+alt+del can't end the task. even if ended, when i try to run sc2 again without restarting, it will hang there again.
anyone experiencing this also?

c2d @ 3ghz, 4gb ram, ati 4850, raid 3x 160gb hdd shud be more than enough to run sc2 IMO..

not even maxing my graphic setting yet.

The game is perfectly fine even in major battle of 4v4, the only problem I am having is tabbing in and loading time

i3 540
asus p7h55-m
ati 5750
4gb ram

1280 x 1024 high
60 fps at menu
fps drops to 10+ when 3v3ai...

anyone experience that too?

My rig:
Processor: i5-750
RAM: 2GB DDR3
GPU: Radeon HD5770 (overclock to 920/1380)
Win7 32-bit

1920x1080 all Ultra.
Frame rates are smooth, but drops to around 30+ when too many units.

However.. I got a problem. The game freezes and jerks when i start any map (even campaign and custom games) This happens for about 8 seconds. After that it becomes smooth.

Why does this happen?

i5 650
1x2gb kingston DDR3
1TB Samsung F3
ATI 4670
Windows 7 64bit
Game graphic settings on High
Resolution=1440x900
Internet bandwidth=streamyx 1Mb

I also Face jerkiness sometimes in the games which i believe is the Bnet server problem...

I'm also having this problem on every game, when loading bar load finish dont press any key yet & wait until your harddisk led is not lit but only blinks, this always work for me as the game won't lag when starting. Maybe due to lack of ram as i'm using 2gb of ram, better get 4gb maybe can solve this problem.
