Magic trick to render faster with just a clicks

Go to Render settings>Advanced>Hardware>Photoreal Devices & check mark both CPU & GPU (Your graphic card name) Also check mark OptiX Prime Acceleration.

In Interactive Devices, check mark both CPU & GPU too.

Why?

In render process, your CPU is always utilize for 100%; whatever you check or not, it doesn't matters.

How?

If you check only CPU, render process is being slower, because your GPU's memory can't be used;

so that it uses your computer memory(RAM).

If you check only GPU, render process is faster, but it will utilize your GPU;

so that it will load on your GPU; & your GPU can be sick & can be less your GPU's Life.

But if you check both, render process is faster without utilization of your GPU.

Your GPU is used just for space(Memory) to put your Graphics.

Your GPU doesn't utilize much, & can be save your GPU's Life.

Note: OptiX Prime Acceleration should be check in all cases, to accelerate the process.

To check this process, right click on taskbar & select Task Manager>Performance.

You can view, manage & change process to get best result, after viewing Task Manager.

Just try it!

Thanks.
