Optimizing my pc5/3/2023 ![]() But if your project only requires 512mb of RAM, getting 4GB will not make blender render any faster. ![]() However, that said, NEVER let your computer run out of memory, HDD based swap is hundreds of time slower than memory, and thus if you encounter excessive-thrashing, get out and buy more memory, or lower the complexity of your scene. Get the amount that suites your project and wallet. RAM size: Depending on the complexity of your project, this will vary from 512MB to 4GB. *Hardware SelectionIf you are lucky enough to be building a computer system from scratch for computer graphics, please keep a few pionters in mind: Set Xpart and Ypart to 1 for best performance Reduce render size and antialiasing quality Use Vector Blur composite instead of ‘MBlur’ If ray is used, play around with the Octree Resolution, usually larger value gives better performance when polygon count is high and vice versa. Disable Raytracing (‘ray’ button) when raytracing is not used. ‘Optimized-builds’ - Usually fully stable, yet faster version due to the specific compiler optimization used ‘CVS-builds’ - Daily version of blender that contains new features not yet formally release to the public and Īlthough “Optimized Builds” and “CVS builds” are usually stable enough for production use, do use official builds when troubleshooting. If Blender is behaving strangly(ie crashes, display corruption or bugs), please make sure you download the official blender version only from. *Blender Binary Optimization (Overall performance gain: 5-30%) However please do not over-do these, defraging 1 time a day or run regcleaner everyweek is excessive and will probably age your computer faster. The less obvious: Defrag(increase disk access speed), remove old applications and files(to make sure you have at least 20% free HDD space), clean out the registry(deletes old entries), and disable un-wanted start-up programs(to conserve memory and free up more cpu time for the foreground taks: blender) via msconfig.msc(on XP). (The driver updates is especially true for graphic cards, so make sure you head over to or or ati.com, as the case might be, and download the latest drivers. The obvious: Make sure your PC is virus/malware free and that you obtain the latest software updates and hardware drivers from the manufacture’s website. *System-Wide Tuneups (Overall performance gain: 5-30%)
