Bottleneck calculation for Intel Core i9-9900X and NVIDIA GeForce GTX 1080 with screen resolution of 1920 × 1080 pixels for No Mans Sky.
Intel Core i9-9900X is too weak for NVIDIA GeForce GTX 1080 on 1920 × 1080 pixels screen resolution for No Mans Sky.
This configuration has 10.3% of processor bottleneck .
When playing games your graphic card won't perform on maximum possible performances (won't be utilized to the maximum), because you processor won't process and deliver data fast enough. This theoretically means that utilization of you processor will be on maximum and the potencial of graphic card will not be completely used.
While playing No Mans Sky game, processor Intel Core i9-9900X will be utilized 100.0% and graphic card NVIDIA GeForce GTX 1080 will be utilized 89.7% .
Processor bottleneck is worse, than graphic card bottleneck, because utilization of your processor will be on maximum and it will throttle other programs that are ran in background. Also you won't experience maximal performances that your graphic card offers.
You can resolve this by upgrading your processor or by downgrading your graphic card. Downgrading your graphic card doesn't make much sense and in that case is better to leave current graphic card in you computer.
