Bios Optimization for e-Sports.

Gaming and mouse response BIOS optimization guide for modern PC hardware.

  • Windows 11 latest version
  • UEFI installation
  • Update drivers to latest version
  • Equipment must be compatible


The closest you can get this to 100.00, the better.

Memory strap (Memory Multiplier):

100:100. 100:100 should obviously provide better results since it matches BCLK. Memory with lower frequency and lower timing can reduce latency.

EIST, C-States:

Disable as many of these as possible because they bring a lot of lag cause of dynamically changing the cpu frequency.

Execute Disable Bit:

Is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. I just disable it.

Intel Virtualization Technology:

Disabled for any gaming PC if u dont use VirtualBox etc.

1394 Controller:

Probably 99% of people don't use it.

On-board Audio:

Enormous input lag. Should be disabled.

On-board Video:

Disable unless you use it.

HPET (High Precision Event Timer):

HPET is a hardware timer used in personal computers. Disable to lower input lag and DPC latency.

Secondary LAN:

Disable to lower DPC latency.


For each processor core that is physically present, the operating system addresses two virtual (logical) cores and shares the workload between them when possible. Turning off hyper-threading gives more fps in CS:GO.

UEFI vs. Legacy Boot:

Legacy tends to be better with a more classic mouse movement. PC will not boot if u have installed UEFI OS or have GPT filesystem.

CPU Power Phase Control:

Extreme / Full.

CPU VRM Switching Frequency:

Manually set 500 Khz or higher.

Legacy USB Support:

Usually have to leave this enabled in order to get back into the BIOS but sometimes will have better mouse response with it off. Varies highly by motherboard.
