Re: Potential HD Mouse Extensions API Specification [ETA by 2025]

syscall is "expensive" but manageable on many systems; As stated that result was with mitigation's (Meltdown...). With W10 1703 and no mitigation's the same HW and clocks produce https://i.imgur.com/LbPMQQt.png Result perhaps similar to https://i.imgur.com/pqfeQPv.png https://twitter.com/cpugoogle/...

Re: Potential HD Mouse Extensions API Specification [ETA by 2025]

instead of saying stuff without claims why not show us some measures? :lol: its always the same "nothing matters" keywords "supposed to be fast" "negligible" "should be less than a microsecond" so. since you measured it why not come with measures and reply with that instead of random fog guesses? T...

Re: Potential HD Mouse Extensions API Specification [ETA by 2025]

Looking at raw input windows API, both GetRawInput and GetRawInputBuffer functions have a syscall overhead. Syscall is supposed to be fast. Don't know why you mention context switching as it's not used by Sycall instruction. For me a GetRawInputData for mouse call takes around 4200 cycles once it's...

Re: Human Benchmark implemented in C++ DirectX9

W7 was run with 480Hz refresh while IIRC the W10 20H2 result was with 60Hz refresh, no specific optimizations. Generally click averages are lower with higher refresh but maybe I should really run those tests with sub 1ms click latency. Edit: Mouse click latency ~0.3ms, W10 20H2 https://i.imgur.com/Q...

Re: I have the new Razer 8000 Hz prototype gaming mouse on my desk.

Also usb controller from intel polls each 50us. I think you mean interrupt moderation as Intel polls to 125us. Polling can occur between USB Host and device, interrupts occur between USB Host and CPU. They are not dependent on timer resolution, for instance one can record 8k mouse data with 0.125ms...

Re: Human Benchmark implemented in C++ DirectX9

5 frames seems way to long; Exactly the point. W7 ran with VSync and 25Hz refresh (40ms) showed 5 to 7 frames. https://i.imgur.com/VBea1SF.png Stranger still, a real human test of W7 with VSync enabled and 60Hz refresh and what happened to mouse click latency? https://i.imgur.com/z547sac.png And W7...

Re: Unable to get refresh rates above 500hz to display in as a selectable refresh rate.

Cool, I didn't know that. Thanks for the information, will take a look at ToastyX.

Re: I have the new Razer 8000 Hz prototype gaming mouse on my desk.

which sensors apart from 3050 adjust LOD without affecting dpi? if it's SQUAL related shouldn't it be pretty much all mouse that has a SQUAL feature? like the roccat and mionix stuff from 2012. those were avago 9800 btw. Specifically SQual and Shutter are read only registers so since they cannot be...

Re: Human Benchmark implemented in C++ DirectX9

TBH I'm more concerned with the synchronized tests. I get much the same results if I test with OpenGL but might be something to do with my system or testing. Would be good to see if others experience a big difference (~70ms) when running with VSync off against a set refresh of 60Hz and VSync on for ...

Re: Is it true Ryzen has higher input lag than Intel? Is there conclusive data to prove this?

I thought applying useplatformtick tweak forces using HPET if it's enabled in BIOS. HPET has both a counter and timers. UsePlatformTick invokes an HPET timer as the system timer or in the event there is no HPET then uses the RTC and uses interrupts. UsePlatformClock invokes the HPET counter as the ...
