UnverifiedFor highly parallelizable tasks such as batch image processing, GPU parallel computing can be one to two orders of magnitude faster than CPUs.79% similarUnverifiedThe trade-off of the hybrid offloading mechanism is that generation speed will be slower than in pure GPU mode.79% similarUnverifiedIf VSR is run using only a CPU, the speed gap compared to a GPU can be as large as tens of times.79% similarUnverifiedIf rendering is slow but GPU utilization is extremely low, the problem is almost certainly in the configuration rather than the hardware.78% similar
