Hello,

I just want to be sure of this but I think that my CPU is bottlenecking my GPU if I understood right when I read about it.

I was playing battlefield 4 a while ago and my cpu usage was at 100% and gpu at about 50% if I look from right spot.

Specs:

CPU: Intel Core 2 Quad Q8200 overclocked 3.19
Motherboard: Asus Motherboard
RAM: 4GB
GPU: MSI GTX 750ti OC Edition 2048mb
PSU: Corsair something.. 450W

What do you mean if you like from the right spot? I wouldn't imagine that the 750ti would bottleneck your CPU, albeit a bit dated but still a decent contender. What kind of fps are you getting? I know that at one point I was getting really poor performance where my GPU wasn't being utilized fully for some reason, a system wipe fixed this issue for me.

I would say there is a bottleneck. Usually with gaming, you aim for the opposite, less than 90% CPU usage, and near 100% GPU usage.

I looked GPU core Load and it was about 60%-80% and I get about 30-60 fps in bf4, depends of the map. But in DayZ I get max 30fps, but in the cities 15-20fps (dont know if its because the bottleneck or because its early alpha)

Day Z is very CPU intensive and horribly optimized, it's normal for you to be getting bad fps in that game with small gpu usage, every one does including my rig. I wouldn't worry with that game, if your others work fine I think you are ok.
