I am using blender 2.77a on windows 10. I intend to do work in separate blender thread(modeling, texturing..small tweaks) while I put my finished frames to render. While rendering blender uses 100% GPU and only 30% CPU.
I am facing serious lag while running another blender process, however I can run other windows applications smoothly as I still have like 70% CPU and enough memory.
I am sure there is possible solutions as I intend to run another blender process on CPU only. Any suggestions are welcome.
