He guys, in the bios settings i set hyperthreading to disable and now i get like 700 to 900 fps on minecraft, with hyperthreading only 100 to 200, what is the reason for this, will this also have effect on heavyer games like battlefield 3, with hyperthreading lower fps that without?

When hyper-threading is enabled the queue for out-of-order execution on the processor is halved as it is split equally, not dynamically based on workload in the last few nanoseconds.

For some software this has a HUGE impact, more so than the gains of HyperThreading.

Some stuff runs MORE than twice as fast with it, other stuff runs less than a QUARTER as quickly with it.



It's Resource Contention on the CPU itself, the current AMD processors (FX-#### series) are also notorious for this, more so than the Pentium 4 was.
