I know what you are saying, but just because a CPU tops 100% usage in game doesn't mean you can't still play it decent.
Thats all. I used to play Shadow of Tomb Raider with a Core i5 3570 + GTX 1060 6GB, and the CPU also tops at 95~100% usage all the time, but still the game was very very playable. Heck I even used the same machine to play BF5 campaing, it wasn't perfect, there was some roughness when changin scenes, but it was still very playable, and I did the first 3 chapters without hiccups.
The video shows one case scenario, with an even lowest Core i5 7400 which only tops around 3300MHz on all core boost. The 7600 should top around 3800~3900Mhz on boost so the performance should be a bit better.
Also the OP never said at what resolution and detail settings the game is. And in fact, we don't even know if the GTX 1060 is the 6GB or the 3 GB version, that can also impact the performance of the game.
Perhaps all the OP needs is to play a bit with the game settings, make the CPU work harder.
Agreed. OP just need to know if 100% CPU usage is killing the gameplay for him or not. I do 100% agree with that!
But it will always depend on how many frames are being achieved.
Let's say, if you have a 100% CPU usage on game X, but you still have more than 60FPS and you have a 60Hz panel, well, theres no problem at all. Agreed.
But if you have a 100% CPU usage and frames droping to less than 60, reaching 40 or even 35 frames, this bottleneck is killing your performance and maybe is holding back your GPU performance.
About Shadow, my old i5 2500k@4.4Ghz have killed my gameplay (rx470 OC droping to less than 70% Usage). Yes, in the major part of the game, I could keep 60FPS, but sometimes it was not possible, having drops to 35, 40 or 45, killing my framepace and my generally experience on the game. Updated to Ryzen 1600 and I have 100% GPU usage all the time now. Much better frames, keeps 60FPS almost all the time. When it's not possible, its because my GPU is holding back my general performance.
But, still that, it was my experience. For some people, anything above 30FPS is absolutely playable and drops are perfectly acceptable, even stuttering here or there, which is often caused by high CPU usage.
