◘ Improving Performance
In this section, I'll recommend some things which are guaranteed to help SC2 performance in some way. I can't tell you exactly how much FPS you'll gain, but on average, it's like 10-15 FPS more and up. It all depends on your system. ♦ Large address aware ♦
This will allow Starcraft to use up to twice as much RAM, this can very effective in improving low end FPS if you use a 32 bit operating system. The difference is much smaller on a 64 bit system. This can fix a wide range of memory issues. Remember that to use this effectively, you should have 4GB of RAM or more. Effects may vary. Download it here.http://www.techpowerup.com/forums/attachment.php?attachmentid=34392&d=1269231650
That links directly to the file, so it will download automatically. Unzip and open up the executable. Once you've opened it up, follow the steps.
Step 1, select the SC2 executable (.exe).
Step 2, check the check box
Step 3, Save.
Done!♦ Razer Game Booster ♦
This will help on old and new systems alike, it will improve game stability and FPS. Here is a link to the official site. http://www.razerzone.com/gamebooster
No worries, it's safe. Be sure to click the download button for the windows vista through windows 8 version and not the XP version. That is, unless you still use XP.
Once you've installed it, open it up, you will need you to make an account. Make it and don't forget to verify your account before attempting to log in for the fist time. Once your in the program, click the add symbol and get the SC2 shortcut you applied Large Address Aware to.
The boost settings are good as is, but to get some more performance, click utilities. Then click others from the drop down, then check Explorer.exe and "launch game on game desktop". Hit apply and you've just configured Razer Game Booster to make your game preform even better. Keep in mind that the 2 settings I had you check will make it so that you can basically do nothing but Starcraft when you run it from the booster. Not to worry, Your PC will return to normal after the game closes. There is another thing you can do as well, go to tweak, then click optimize, this will apply a set of performance enhancing registry settings to your PC, restart to fully apply them.
In order to take advantage of Razer Game Booster, you must launch the game from Razer Game Booster. It will run in an idle state in the background once you open the launcher, unless you close it from your taskbar shortcuts or task manager. It is very lightweight though.♦ Unparking your cores ♦
Create a restore point before this just in case! ONLY for those with multi core CPUs. This should be fairly safe for most people. Keep in mind that this can effect temperatures a bit, but more so for laptop users.
This is a tweak that will essentially keep all your cores 100% ready for work at all times. It is a registry tweak, but this download will make it simple for you. http://www.coderbag.com/Uploads/Unpark-CPU-App.zip
That link goes directly to the file, so it will download as soon as you enter it in. Unzip it and open the program up. Below is a quick how to video I found. You must restart your PC before it can take effect.https://www.youtube.com/watch?v=eyo6H3W-vu8
NOTE: Unparking cores has been show to cause crashes in some rare cases, this mainly occurs among laptop users. Luckily, any issues caused by unparking can be reverted.♦ Setting up graphics properly ♦
Yeah, you may have a good GPU and all, but for some reason, your FPS is not where you'd like it. Tomshardware has determined that the CPU is the main bottleneck for this game, so setting the graphics properly can yield the best looks at the best performance. First, set models to low, this does not effect the "quality" of the models so much as it makes them less individual. Chances are you wont notice much of a difference, so set it to low and enjoy better FPS, especially in big battles. Also turn other settings that use the CPU off or low. These settings, again, don't effect the overall look as much, so go ahead and turn them down. These settings include physics, which I'd set to medium or low, reflections off, and effects low-medium. This will help regardless of how good your CPU is. It will greatly help those with a decent GPU but a somewhat lacking CPU. With the other settings, set them as high as you're comfortable with. test configurations out, you can see the FPS by hovering over the menu button in game.
If you know you have a good CPU, but a crappy GPU, then set the GPU related settings down and all of the CPU settings up. just hover over a setting to find out if it uses your CPU or GPU.
Once you're done with these settings, try not to change them again. Changing graphics settings later on may mess up some of the variable changes you can make in the next subsection. ♦ Variable.txt edits ♦
The video below shows a couple tweaks for a file in SC2 to improve FPS. Changing the bit depth to 16, which wont effect eye candy that much but yields a good performance boost. And disabling shadows for slower computers. BTW, you have to manually type in bitdepth=16, it's not there by default. don't forget to save the file when you're done. Remember you have to edit the file with notepad.https://www.youtube.com/watch?v=kUh_MElGgoI
You can also try these out. You can just type them in if there not there. (Some of these were copied from Xapti's "The comprehensive variables.txt thread!")
You said wanted to disable the shinny glow on stuff with your settings, you can try these.
hdr = 0
spec = 0
If you did not disable shadows, try these to improve performance.
shadowmapsize=512 (shadow detail. You can also try 256 or 128.)
transparentshadows=0 (Major change for ATI Radeon. cloaked units get normal shadows instead of transparent.)
--------------------------------------------------------------------------------------------------------------♦ Leatrix Latency Fix ♦
This is a simple tweak that will change the way windows treats incoming network packets or something, basically it will cut your game ping in half. I can vouch for this. This will help allot for those on laggy connections. Download this tweak via the link below. It links directly to the file as well, so it downloads automatically.http://www.wowinterface.com/downloads/download13581-LeatrixLatencyFix
Unzip it and run the Leatrix Latency Fix application. All you have to do is click install, then you're done. You must restart your PC before it can take effect.♦ Sound Settings ♦
Go into your settings, then to the sound section. Uncheck "enable reverb", then reduce the sound channels to 16 or 32. This will be hard to notice and can make a good difference with weaker CPUs. ♦ Disable your AV while you play ♦
This won't help much unless you're using a crappy AV like Norton, a resource hog Don't forget to turn it on. (By the way I suggest Avast, it's super lightweight!)▲
