FAQ’s ( Frequently Asked Questions )

Everything you need to know about PC bottlenecks

A bottleneck occurs when one component in your system limits the performance of other components. For example, if you have a powerful GPU but a weak CPU, your CPU might not be able to feed data to your GPU fast enough, causing the GPU to wait and not perform at its full potential.
