my cpu is supposed to run at 2.7Ghz but when playing TB it only runs at .7 http://gyazo.com/ccc78fb96820565eae3700dd005465a0
i have my power setting set to "always 100%" but i guess it doesn't wanna listen...

TB only eats CPU cycles on certain mods, usually ones with high gravity & lots of collisions going on. Also worth noting that online games are calculated by the servers rather than your PC, so it's only single player that gets a CPU hit.

On top of that newer processors are a lot more efficient than older ones, so where an old CPU would be running at a high % a newer type with the same advertised speed would run lower.

yes but im also getting like 5-10 fps

Most likely caused by graphics hardware

hmm, all my drivers are up to date

He said hardware, not software.

Try disable ray tracing? It's usually the option, which eats the utmost resources.
