Hi Everyone, I am having a major problem playing SC2 and Blizzard has been no help to me so far. My specs are as follows: AMD Phenom 8450 Triple Core Processor 2.10 GHz 3 GB RAM Radeon HD 5670 Everything looks great until I get into the campaign. Once I am in the campaign, I get a LOT of lines that are popping up all over the screen. It gets so bad that it is tough to concentrate and play the game. I am running the most up to date drivers and directx. I took a video on my phone and if anyone has an idea what is going on I can send it to you in an email. Thanks in advance for any advice you could give!
Thanks for the reply! I have been trying everything and anything to get this damn thing fixed! I finally pulled my Radeon card out today and tried to run SC2 on my onboard card. I know it would not run it great that is why I bought the new one. The game runs fine (Slow and choppy) but no crazy lines. So I guess this means my video card was overheating... Does this mean the card is defective or just can't handle the game?
Try using caned air to blow any dust out of it. Also, you can try the fix that is normally used on nVidia cards: -Open your Variables.txt file (which can be found in C:\Users\{YourUserName}\Documents\StarCraft II) Add these lines to the bottom: frameratecap=60 frameratecapGlue=30 This may help you keep things cooler. Do you have any issues like this in other games? If you do, then you may have a defective card or need to have new thermal paste applied between the GPU and cooler unit (aka, warranty work if its still covered my a warranty).
No, this is the first time I have seen the problems when I tried to play SC2. I will give this a try and see if I can get it work. Thanks again!!
That didn't help! Below are two links to the videos I took of the screen: http://img825.imageshack.us/img825/7200/sc22.mp4 http://img251.imageshack.us/img251/8126/sc21.mp4
Haha! Thanks a lot for your help! I also just did a support ticket with XFX to see what their thoughts are. Sucks that we have ALL been waiting for so long to play this game and then it finally comes out and my computer doesn't want to agree with the game!
That is really weird. Download Speedfan. It measures heat. Go into the campaign while it's running, then alt tab out and check your temps. Have you tried turning on V-Sync (I think SC II has it). Might be a refresh issue.
I did try turning on V-Sync and it made no difference. I downloaded GPU-Z and got this reading: Date , GPU Core Clock [MHz] , GPU Memory Clock [MHz] , GPU Temperature [°C] , Fan Speed [%] , GPU Load [%] , Fan Speed [RPM] , GPU Temp. #1 [°C] , 2010-08-01 15:48:40 , 400.0 , 1000.0 , 52.0 , 71 , 1 , - , 52.0 , 2010-08-01 15:48:43 , 775.0 , 1000.0 , 52.0 , 71 , 0 , - , 52.0 , 2010-08-01 15:48:44 , 775.0 , 1000.0 , 52.0 , 71 , 0 , - , 52.0 , 2010-08-01 15:48:45 , 775.0 , 1000.0 , 52.0 , 71 , 0 , - , 52.0 , 2010-08-01 15:48:46 , 775.0 , 1000.0 , 52.0 , 71 , 0 , - , 52.0 , 2010-08-01 15:48:47 , 400.0 , 1000.0 , 52.0 , 71 , 0 , - , 52.0 , 2010-08-01 15:48:48 , 400.0 , 1000.0 , 51.0 , 67 , 0 , - , 52.0 , 2010-08-01 15:48:49 , 400.0 , 1000.0 , 51.0 , 67 , 0 , - , 52.0 , 2010-08-01 15:48:50 , 400.0 , 1000.0 , 51.0 , 67 , 0 , - , 51.5 , 2010-08-01 15:48:51 , 400.0 , 1000.0 , 51.0 , 67 , 0 , - , 52.0 , 2010-08-01 15:48:52 , 400.0 , 1000.0 , 52.0 , 67 , 0 , - , 52.0 , 2010-08-01 15:48:53 , 400.0 , 1000.0 , 51.0 , 67 , 0 , - , 51.5 , 2010-08-01 15:50:08 , 775.0 , 1000.0 , 55.0 , 76 , 83 , - , 55.5 , 2010-08-01 15:50:09 , 775.0 , 1000.0 , 55.0 , 76 , 63 , - , 55.5 , 2010-08-01 15:50:10 , 775.0 , 1000.0 , 56.0 , 76 , 50 , - , 55.5 , 2010-08-01 15:50:11 , 775.0 , 1000.0 , 55.0 , 76 , 30 , - , 55.5 , 2010-08-01 15:50:12 , 400.0 , 1000.0 , 55.0 , 76 , 0 , - , 55.0 ,
I have this same exact problem but with my Nvidia card so it does appear to be ATI or Nvidia specific. Mine only happens during the cutscenes. When I am playing the game or viewing any cutscenes running on the game engine they are completely smooth and have no problems. But when I watch one of the pre-rendered cutscenes it goes choppy and I get the funky issue you have. I ran the heat tests and that doesn't appear to be the problem. I updated all my drivers as well. Windows 7 AMD Phemon II 965 8GB DDR3 Ram NVidia GTX 295
If videos are getting choppy, that sounds more like a hard drive issue. Defraging with something like PerfectDisk Pro may help resolve the issue, or if you have a 4200RPM hard drive on a laptop, the drive may simply be too slow. The hard drive could also be in prefailer (in that case, you need to figure out what make it is and download the appropriate tool to run diagnostics on it to reach a "for sure" conclusion). If the hard drive is failing, then the only solution is replacement. It could be any number of less bad things though, such as an old disk controller driver. Need more information on your machine. I would try defraging first. I have added additional information to my FAQ on finding more of your system information in my question "Q. My issue isn't addressed here? What should I do?". Please most more of your system information.
I have an ATI Radeo 9600 gfx card and I have the same choppy playback of prerendered cutscenes. The audio stream playbacks fine but the video stream is like ~2 FPS. The gameplay is just fine although it's low quality. The same problem occurs when I try to playback any high bitrate HD video on my 6 year old system (p4 3 ghz prescott), like a VC-1 encoded HD clip with L2 or higher profile. A L3 profile clip has 45 Mbit data rate and it really saturates the CPU. I think it's not related to GFX card since HD video decoder uses the CPU, not the GPU. I guess the prerendered cutscenes in Starcraft 2 have video bitrates higher than a P4 3 ghz CPU can handle. Since Blizzard added a low profile setting on the gameplay to support older systems, I expected them to also add a low bitrate copy of the cutscenes.
These are artifacts, not screen effects. Artifacts are caused when the GPU is either receiving too little power from the PSU or the drivers are bad. Poor coding in games can cause this as well. 1) Make sure your video card is compatible with the wattage output of your PSU. 2) Try updating your graphics card drivers to the ABSOLUTE latest. If you have the latest currently, you could try reverting to an older version. I have this problem sometimes in Left 4 Dead 1 and I have NO idea why. I've tried everything. But last week I swapped video cards and now it works fine. Quirks, quirks, quirks.
This is a bug with certain ATI drivers and SC2. Its one of the very few they've actually acknowledged because there's a work around for it. (SCV shoots lasers one) http://us.battle.net/sc2/en/forum/topic/248427143 http://us.battle.net/sc2/en/forum/topic/248427331
