Is this right or wrong? Because I want PJ64 to use 99% of my system's CPU so games can run faster.
Clements said:If you have a dual-core CPU, or a processor that supports hyper-threading, this is normal behavoir for all single-threaded apps. For PJ64 to use more than 50%, then the app would need to be threaded, which is extremely difficult to code for. Also, since a 1.2GHz processor is all that is needed to run 90% of games, there is little motivation to add such a feature.
Correct. Task Manager (or any CPU monitor) is a little quirky with HT, because there are two logical processors, but only one physical one. The physical processor's full potential can be used in a single thread, but Task Manager still believes there is another equally powerful processor that is not being utilized - which is not true. Together, the two logical processors can only use as much CPU time as is available from the one physical processor. How this time gets split up varies, but the Task Manager doesn't account for this by weighing one processor as a greater or lesser percentage of the CPU's total ability.Clements said:- Unless I am complete wrong about how HT works, it'll only register 50% of the CPU in single-threaded apps.
The Duron being slower is also related to its FSB and how fast it talks to system memory., not just the 64kb cache.
a computer can only go as fast as it can recieve data from the system memory
