is there a way to force more CPU resources to shorten / cut-in-half time it takes to do a still frame render?

is there a way to force more CPU resources to shorten / cut-in-half time it takes to do a still frame render? or is it automaticall set? thanks!

By default CPU is set to 0 meaning no limit is set for cores used. So it should use all cores unless you have changed it.

you know, i just switched one of the scenes i did earlier to Vray GPU. it worked, 4mins to render. the 4 scenes i did earlier were 45mins and 60mins range. so hey, i guess as long as i don’t use an unsupported feature (which i hardly ever did anyway) i can stick with GPU rendering.
