 AMD has silently released a utility that fixes time stamp
counter (TSC) issues with dual-core AMD processors such as the Athlon
64 X2 and Opteron. The AMD Dual-Core Optimizer utility is a driver that
synchronizes the time stamp counter on both processor cores and
improves game compatibility and performance. Time stamp counter issues
occur in older games that are incompatible with multithreading and
would run too fast or out of sync. Issues also occur in newer games and applications that have compatibility issues with processor affinity like Need For Speed: Most Wanted. Affinity issues typically required users to bring up the task manager and set the processor affinity manually or performance would suffer dramatically. The AMD Dual-Core Optimizer utility could possibly be the rumored “Reverse Hyper-Threading” patch that would improve single thread application and games performance by having dual-core processors show up as a single core processor in applications. AMD has declined to comment on "Reverse Hyper-Threading." AMD’s Dual-Core Optimizer utility version 1.0 is available from AMD’s website. The utility release notes shows it as being released on March 22nd, 2006 which is strange as AMD has made no mention of the utility publicly. The utility also installed on Core Duo and Opteron systems.  Download: AMD Dual-Core Optimization Utility 1.0 |
