Hello there, so I am just wondering whether my Intel core i5 4460 is bottle necking my GTX 980 TI, because the only way to get 90%-100% out of my GPU is to play at 4k, yielding a very respectable 40-50fps. However, considering my GPU is capable of higher frame rates at 1440p and 1080p, why is my GPU usage only at 40%-50% when playing at these resolutions- extremely annoying!!! Any help would be much appreciated.
