Blender is a powerful 3D modeling software that can help create stunning 3D models and animations. However, to truly take advantage of Blender’s features, one must optimize the program to get the best performance while working with it. Here are some tips on how to optimize Blender for maximum performance and efficiency.
- Update Your Graphics Card Drivers: It is important to keep your graphics card drivers up to date as they contain the necessary software and tools to render graphics in the best way possible. Updating your graphics card drivers ensures that you get the best performance out of Blender.
- Using a better render setting: If you’ve a NVidia GPU, blender won’t always choose the best settings for you, so here they are(You can find this window under Edit > Preferences then System)
The most important parts are the Render to be set to “OptiX”(for GPUs RTX 2000 and above, Cuda otherwise). For AMD, select “HIP”, and finally for intel Arc use oneAPI.
I also recommend unselecting either your CPU or GPU in “Cycles Render Devices” as, like said in sections below, each one of them have a different preference for tile size, and are likely to slow down the other during render.
A bit more advanced:
Render with Cycles: Cycles can take advantage of your GPU power, making it the fastest when you wish to render something and still make it look good. You can find the setting at the very top of the TV-looking icon on blender(named “Render Properties”).
Use tiling: This makes blender basically split the render into squares of the specified size, which helps rendering faster. The recommended tile size for CPU rendering is 256(so 256×256 squares), for GPU it’s 2048. You can find this setting by scrolling down a bit further under Render Properties:
Reduce Anti-Aliasing: Anti-aliasing is a useful tool for smoothing out edges, but it can also greatly reduce rendering speed. If you don’t need high-quality anti-aliasing, you can reduce it in the “Viewport” tab in the Edit > Preferences:
Disable Auto Save: Auto save can be useful for keeping your work safe, but it can also slow down blender, mainly if you’ve slow storage(say, Sata SSD or a Hard Drive). To disable auto save, go to the “Save & Load” tab in the Preferences panel and uncheck the “Auto Save” checkbox.
Enable statistics: Make sure that statistics are enabled as soon as you start making models, so you can keep track of triangle and vertice count. This way you wont accidentally increase those too much which will end up slowing down the whole program.
By following these simple tips, you should be able to maximize Blender’s performance and get more out of your 3D modeling experience. Making it a lot better to use when editing more complex models/worlds for your game.
However, if blender still isn’t running well, maybe give some alternatives a try. Here’s a list of the top 5 alternatives to Blender.
