Gaming and mouse response BIOS optimization guide for modern PC hardware - Page 292

post #2911 of 3506
There's one tweak that's unmentioned on here, IRQ priority via registry.

-HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl\
-Create new DWORD
-Name: IRQ#Priority where # the IRQ you want to boost priority.
-Value: # where (1 is highest priority)

Restart your computer and feel the difference in-game.

Most people have increased the priority of the CMOS clock (IRQ 8) which has an overall impact to the system, however you could try boosting the gpu, mouse, cpu IRQ priority.

This works on Win 7, 8, and 10.

Interesting. What IRQ you priority and why?

Does Process Lasso priority IRQs auto or change anything related to it?

I dont know process lasso very well, I have tested modifying IRQ priority for usb, gpu, cmos and system clock. CMOS (8) and system clock (0) IRQ produced positive results when one is set to priority 1, mouse and keyboard became more responsive from a gaming perspective.

The IRQ priority thing makes no measurable or perceptible difference that I've been able to find, so I'm extremely dubious as to whether it actually does anything. But feel free to use it because it's not going to make anything worse.

Process Lasso is basically just a dressed up version of the Multimedia Class Scheduler service. Personally, I prefer to not use Process Lasso and disable MMCSS. There is more overhead involved in dynamically managing process priorities than it is able to make up for, in my measurements. It may for instance give you increased peak FPS in a game, but because at least 10% of CPU process time is reserved for low-priority system tasks, there is more variability and lower average FPS in my experience. MMCSS may be needed on some systems though to maintain smooth audio playback and other such latency sensitive tasks. And if you keep your system loaded up with resource intensive processes, say for instance you like to game while having a Twitch stream playing on the other monitor and downloading a torrent in the background, then MMCSS would probably be beneficial.

I've been having all sorts of issues with my computer, keyboard input delay on PS/2 and usb (2.0), as well as usb mouse accuracy/consistency. This IRQ priority tweak seemed to have reduce these issues on both Win7 and Win10.

The keyboard input issues shouldn't exist given it is reporting directly through PS/2 on a low IRQ but in-game I would be doing a series of simple and complex movements in quake3 arena but my character would start miss turns during a jump as if i was still holding a key even though I wasn't. With the priority tweak these issues occur much less or not at all.

Out of all the optimizations in the USB polling thread and this one, this is the only one that has nearly resolved the issue for me with my keyboard movement and mouse consistency issues. I'm assuming there's some sort of issue with my computer or motherboard.

Mouse: Zowie ZA13
CPU: i5 4590 3.3ghz
GPU: Nvidia 560ti
Keyboard: Steelseries 6gv2 Cherry Red
Monitor: BenQ XL2411
Motherboard: Asus z97m-plus

What do you replace # with there for mice priority and others? how do you know which is which number?

IRQs can be viewed in the device manager manager console of windows.

This guide shows you how to see them with pictures.

What's better, dvi-d or displayport?

For latency?

Probably depends on your video card and drivers. On older cards I imagine the answer is DVI-D. On newer cards that don't have DVI-D native it could be the other way around.

That said, it probably doesn't matter to any significant degree. DisplayPort is the superior connection in terms of raw bandwidth and support for DRM checks (sigh).

Can someone give me a TLDR on MSI mode on devices please? Is it helpful, and what devices are good to switch to MSI mode?
