Games not using full power

[ZipurGamign]

I have:
i7-6700
16 GB RAM
GTX 980 4GB

When playing games at max I get low FPS, although they never use more than 50% of RAM, and never over 30% of CPU. When I export from Adobe Premiere Pro it uses 100% CPU.

Describe low fps? 30fps? 60fps and no more? 5fps? Check thermals
