StarCraft II Beta: Game Performance Analyzed

Test System And Settings

First and foremost, we need to stress that StarCraft II is still in the beta stage, and no matter how slick this game engine runs, there may be performance improvements before the game is released.

We tested a solid sample of cards from our Best Graphics Cards for the Money column, and even a few more. We tested AMD boards from the Radeon HD 5570 to the Radeon HD 5870 and most of the cards in between. We also included Radeon HD 5850s in CrossFire mode. Representing Nvidia's lineup, we tested from the GeForce 9600 GT to the GeForce GTX 260.

We chose the newest-available Nvidia 197.12 drivers at first, but these tend to crash StarCraft II on launch. We therefore reverted to the 196.21 drivers for our testing. For the Radeon cards, we used the Catalyst 10.3 prerelease drivers that were publicly available when we tested. Since then, the official 10.3 drivers have been released.

The only surprise we experienced when benchmarking was a 16- or 32-bit color-option inconsistency that changed based on the graphics card we used for benchmarking. In general, almost every graphics card configuration allowed for 2560x1600 32-bit color, 1680x1050 16-bit color, and 1280x1024 16-bit color.

However, not all cards support 1920x1080, so we had to benchmark 1920x1200, and not all cards supported the same color depth at this resolution. We simply benchmarked the color depth that was available to us at 1920x1200, and for peace of mind, we did test both the 32-bit and 16-bit color option on the cards to see if the color depth affected performance. Our results show that the difference in color depth doesn't affect performance enough to impact results.

  • Nice review, never played the original, will have to give this a try. I'm tired of run and gun.

    A small request. Would you be so kind as to include a 4 series Radeon in your next review? Maybe a 4870 or 90. I know that my CF/OC 4770's give me 4890ish performance, but have no idea where this is in 5 series.

    As you used older Nv cards, I will guess that the game is DX11 but DX10(.1) playable.

    With a little luck, a few months from now, I will only need to look at the 5 series charts.

    I have a Radeon HD 4870, and my performance on the Starcraft 2 beta is about the same (usually better) as my roommate, who has 5770. When I'm looking at the FPS it usually sits around the 78fps mark. I couldn't tell you during an intense battle because... well... I'm not looking at the FPS meter. In general, our cards performs about the same in most games we play. The rest of our systems are also comparable, with the exception that he has a significantly faster hard drive than me, which usually only comes into effect on load times (he can load a Bad Company 2 map about 15 seconds before I can load mine).

    Of course our little benchmarking isn't as precise and Tom's is, but maybe that'll give you a starting point.

    This should be 48 fps, not 78. Damn lack of edit.

  • i would have hopped to see more scaling and not so much cpu dependent oh well... also the multi core code hope that will improve cause everyone will soon have 3-6 cores... and if only 2 cores are giving you any advantage i hope they optimize it at least down the road

  • why does fps cap seem so low?

  • I was dissapointed that there were no GTX470/480, since i'm planning on buying them :)
    Other thing that bothers me is a CPU :( i have Phenom x4 at 2,3ghz and as i see this game runs better on faster CPU's :(
    and man, i can't wait to get my hands on this game :D

  • Wow, I did not expect this. I actually made a thread on TeamLiquid.net about preparing computers for this game, but a 3.06GHz i7 and an ATi 5870 getting a lowly 46FPS @ 1920x1200? That's surprising to say the least. People on TL were reporting 50ish FPS at Ultra with ATi HD 5770s..

    It also conflicts (imo) with the LegionHardware benches from about 2 months ago..

  • hmm ... so clearly widescreen is an advantage in the game ...

    anyway I do not like the ground detail in the higher (med+) graphics settings. it looks very plastic and unnatural to me ... I guess for all the eye-candy, my most used setting will be low ...

  • If the game is truly as CPU bound as these benchmarks suggest, what the hell is blizzard doing not making it multithreaded...

  • bmaddno GTX480/470??


    I'd go so far as to suggest a 470 or 480 would be overkill for this, just as they'd be overkill for WoW.

  • 920 i7 @ 3.9 with 5870 @ ultra setting and 1080 res, i get around 150-200+fps even in crazy battles (from frap)

    p.s pre-order starcraft 2 at amazon or gamestop and get a beta keys (for those who want to play NOW!)

  • Works fine with Agena 9600 + 9600GT (197.45) on ultra preset @ 1680x1050. Latest v10 patch (one with editor). Have not noticed any slowdowns during battles.

    Offline version is limited to 1 player and 3 AIs. Not sure how online game play would be - don't have a key. Maybe playing against 7 AIs will lag.

  • Lovely to see a title with proper level of detail at the medium setting. The lastest crop of games from the past years, usually looked like crud when you even get to medium settings.

  • Im gonna agree with these other folks up above. Sure the 5770 is a lower newer card, but most of us are rockin older cards like the 4870. Why not review with some of those, instead of just givin a review with a new card that just came out a few months ago ? No offense inteded to Toms, i read the page everyday, but lets be more realistic here. Those cards just came out,a greater majority of your reader arent even using them yet.

  • Hopefully they've gotten around to fixing that nastiness in Win7 so I don't have to leave my display settings window open in order to get the colors to display correctly like I have to do when playing the original StarCraft.

    Oh... and thank goodness for the widescreen options now!
