Goal: To objectively measure the impact of clock speeds, Hyperthreading and memory tuning using the built in AC benchmark
Process: Every iteration was set via bios with a clean boot into the OS. Then waited 5mins for the OS to reach a steady state. Content Manager was used to run the Benchmark with CapFrameEx to manually capture 92 seconds of the highest stress placed on the systems. GPU (2080ti ) was temp controlled and OC'd to avoid being a bottleneck
Tools and Equipment used:
CPU = Intel 9900k
Mem = Team Group 14-15-15/3600 1.45v XMP kit
Mobo = Asus Z390 Apex
GPU = Gigabyte Windforce 2080ti
PSU = 850w
OS version = Windows 10 2004 with latest patches
GPU driver = 456.71
Capture tool = CapFrameEX 1.5.5 https://www.capframex.com/
Nvidia Control Panel Settings:
Content Manager Video Settings (note 16x AF is being forced via NVCP):
CSP and SOL are *NOT* used
Results as FPS Numbers:
Results as Percentages:
Findings:
Conclusion:
Nothing above required doing more than tuning what you have. In our sim analogy, it's effectively fine tuning the car setup. Just as a well tuned car setup will increase your performance, so will a well tuned PC. This extra performance and especially the bump in low fps become critical for VR users who are subject to stuttering and reprojection. Getting those minimums up goes a long towards a smoother experience so get to it!

Findings:
- Out of box 'plug n play' settings leave close to 30% performance on the table compared to the highest tuned option
- Enabling XMP on a good kit and manually setting your CPU overclock is an easy step to maximizing you system. This requires minimal user knowledge and can be done in a manner of minutes
- Manual Memory tuning over XMP is worth 300mhz of CPU clock speed increase
- Hyperthreading has no impact on the frame rate
- The AC engine scales in CPU clock speed in a linear fashion. This means adding more CPU clock speed is never a negative
- The AC engine responds in a similar fashion to mem tuning
- The AC engine is really well optimized as it responds predictably to any aspect of tuning whether it's cpu, mem or gpu @StefanoCasillo Well done here! not many engines respond like this
