Below you will find a few tips that should smooth out game play. It's something that won't work for everyone as it depends on the PC setup. No, series it does depend on the PC setup. Tip 1: Update Your Drivers Update your drivers to the applicable application/game you are using. Also, visit the game's forum (or developer's homepage forum) for any information regard patches, etc. Tip 2: Check your CPU Frequency in Game Check to make sure that your CPU and GPU clock rates are where they are suppose to be. Using GPUz and CPUz, etc will help determine this. There is also another trick for Win7/Vista users. Use the Resource monitor and check to make sure that your Max CPU Frequency is at 100% or more while in game. You can check this by playing the game in window mode while using Resource Monitor. If the % Maximum Frequency is anything other then 100% or more while in game then it's reporting that frequency of your CPU as lower then it's default (or whatever your have it set to). What that means is that if you have it set to 3.60GHz Resource Monitor is not reading that frequency in game. This isn't normally the case for i7/i5 users. But for those still using C2D/C2Q, etc you want to check your bios to determine if features like CPU TM Function is disabled (refer to your manual for details). And make sure you've set the appropriate Power Options. Please note that you won't see Minimum and Maximum Processor State under Process Power Management unless either SpeedStepping or Cool and Quiet are enabled. In any case setting both to 100% or using the Performance Option should allow 100% Maximum Frequency but it's on all the time now. Another option is making a registry edit. This is more for C2D and C2Q (or earlier gen CPUs). And, you have to confirm that your % Max Frequency isn't 100% while gaming before you do this. What you do is open up regedit and do a search for 0cc5b647-c1df-4637-891a-dec35c318583 using Edit, Find (this key is found more then once in the registry). Within each of those keys you will find 'ValueMax' with a value of 100. You want to change that value to 0 (using Modify). To change it back you modify 'ValueMax' and select Decimal and enter 100. Once the changes are done (to either enable or disable this tweak) reboot your PC. Sidenote: Be careful when you have features like SpeedStep, etc enabled when using LoadLine Calibration. For some C2D/C2Q, etc users it's best to not use LLC when SpeedStep etc are enabled. Tip 3: Use the Exclusion List For some who use antivirus programs you want to use it's exclusion list to add the game's .exe. You also want to add those files that for whatever reason are modified each time you play that game. For example the game's save.sav file. Those files are usually found somewhere in the: -My Document subfolder -AppData subfolder -steam\userdata\some random number\ You will need to do a search for them in order to find them and place them in the exclusion list so that your antivirus program isn't trying to scan while you game. Also note, some antivirus programs have a feature that turns off it's resident scanning while in game. You will need to research this on your own to find out if such an option exists. Tip 4: Process Idle Tasks For some, processing all idle tasks that are scheduled can work wonders on performance. All you do is open up CMD with Administrative priviledges and type: Rundll32.exe advapi32.dll,ProcessIdleTasks Then close the CMD screen. You then open up Task Manager and look at CPU usage. Once everything seems to settle down start your game. You shouldn't need to do this every time you boot your PC. But that really depends on how you have things setup and how that portion of the OS is working on your PC. Tip 5: Defrag Defrag your hard drive. Yes, it really does work wonders if you have a high fragmentation rate on your hard drive. There are plenty of programs out there that are capable of doing this. However, it's best to remove the pagefile 1st before defraging your HD which will require a reboot in order to remove the pagefile. It's fairly simple, you type in system in Start's search bar > Advance System Settings > click on Settings from Performance > Advance Tab > Change button. Select the drive with the page file and hit the 'Set' button then hit the ok button (you maybe asked to hit it again). Then reboot as needed. Just make sure you have at least 4Gigs of ram. After the reboot start the defraging process. You can even use Windows defrag program if you like. Once completed go back and re-establish a pagefile and your all set. Tip 6: Delete the Game's Cache In some cases deleting the game's cache can help improve performance if the game is recently updated. In one example, SCII, you can delete the game's cache by going to: \ProgramData\Blizzard Entertainment\Battle.net\Cache and delete the contents found there in. Restarting the game will re-populate it's cache. Keep in mind that not all games have this option or may not work well if you delete the cache files. Do some research on that particular game first before deleting it. Tip 7: Turn off Vsync If you are experiencing lower then normal performance and have vsync on (either in game or by driver) disable it. Note: If you still would like to limit the frame rates somehow do to special circumstances (ie: odd stuttering, etc) then try a program called dxtory. Set it to your minimum frame rate and you should notice a much smoother game play experience. Depending on the frame rate that limited it should also help in tearing. Tip 8: Turn off all unnecessary processes You can killing certain none essential processes from windows task manager like mom.exe (games still work with it disabled and clicking on the CCC icon re-enables it). Use caution as killing certain process can be harmful or yield no performance increase at all. Note For example: Mom.exe PnkBstrA.exe (for none punkbuster games) etc. However, there is a program called Process Lasso that can improve a PC's responsiveness and stability. It's debatable if one should use it or not. If you have a good control over your OS's processes, etc you will probably not need it. Tip 9: Reinstall PB If you are playing a PB enabled game online and you believe (for whatever reason) it's contributing to whatever problem you are experiencing then try this: -Use pbsvc.exe to uninstall PB -Reboot -Open the 'Run' Command box and type: %USERPROFILE%\AppData\Local\PunkBuster\BC2\pb and delete all entries except for pbcl.cfg (if you are using it). -Use pbsvc.exe and reinstall PB -Use pbsetup.exe to update the files you replaced. More information about this can be found in this post. Note: I added the pbsvc.exe part because reinstalling both pbsvc.exe and pbsetup.exe files, etc seem to help. Tip 10: Check for Ati3duag.dll or Atiumdag.dll in the Install Directory of your Game If Ati3duag.dll or Atiumdag.dll is added to the install directory of your game & a newer one offers better performance for that game just rename the older .dll found in that game directory (not the windows sub directory). Tip 11: Adjust the Appearance and Performance of Windows Type Adjust the Appearance and Performance of Windows in Start's search box and open up the Performance Option window. Make sure you are using the Visual Effects Tab. Select Adjust for best performance. Then start the game. Tip 12: Clean/Remove the Dust from your PC (PC is unplugged and has no power from wall socket.) This goes without saying that a can of air from Walmart (or your local store that sells it cheap) is ideal for cleaning the PC's -Motherboard -Ram -PSU (for thorough cleaning you may need to remove the cover but this is for someone that knows what they are doing. For example, the PSU is unplugged from the wall socket, etc) -DVD Drive -Video Card: This is a tad more technically involved. You would need to remove it from the PC. Remove the cover and HSF combo from it (and back plate when applicable). Then clean the HS contact area as well as the gpu die from old thermal compound (90% or higher Rubbing Alcohol or Thermal Compound Remover). Clean the video card area from dust using a can of air. Also clean the HS Fins and fan area. Then you have to reapply good thermal paste without it touching the other components of the gpu package (those diode looking thingies next to the gpu die. You only want thermal compound on the gpu die. Note: Cleaning out the fin area of the HS is essential for OEM designed video cards as they can be hard to get to. A can of air may not be strong enough to do the job. An air compressor would work but must be properly pressurized (using a lower setting) so you don't damage the HS fins. Also note: don't damage the thermal pads. Make sure you pay close attention to avoid unnecessary contact. -CPU: Same applies as the video card clean. Clean the HS fins, fan and clean and reapply thermal compound. Disclaimer: You perform these tweaks at your own risk.
