I've already reduced input lag without rebooting. It's very noticeable.
Very unlikely, as changes to the registry require a reboot to be activated.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\services\nvlddmkm]
"DisableWriteCombining"=dword:00000001
I cant find this in my registry.
Oh my god. Even after editing I realized that path is not correct
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\nvlddmkm
This is the correct path. Things should look like this if done correctly. You obviously need nvidia gpu for this , as well as restart pc for it to apply.
Sorry for baiting everyone with the incorrect path, not once but twice
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\services\nvlddmkm] "DisableWriteCombining"
What number should be filled in here? 0x00000001 or 0000001 or 0x1 or 1? Thank you

If you double click on that one, it should open this window (see attached). Put a 1 there to disable Write Combining. Put a 0 to enable it again, should you run into issues.

even with error mouse feels even more snappier than prior to using riot profile.
edit
also once added missing reg entry DisableWriteCombining 1 rebooted played doom eternal and mouse felt off remove and snappy again
This probably means all settings were applied except the once it didn't find that's why it gave the error that is a good thing
so the important settings that still exist are getting applied anyway.
I remember I saw in some forum that the disabled writing combing tweak is only for GTX cards or something like that also like any tweak you might experience different results from everyone else so test and decide for yourself if it is working or not.
Any GPU that can use drivers below 457.30 can use the "dword". It's a matter of driver implementation. I can confirm this because I have the source code. All drivers after 457.30 to my immediate knowledge is deprecated along with many other settings.
I use the 471.96 driver but I can still set DisableWriteCombining in the registry so it doesn't work?

DisableKmRender (0)
DisableKmRenderBoost (0)
EnableDirectFlip (1)
EnableIndependentFlip (1)
EnablePerformanceMode (1)
Those Settings are Default on 572.16, but can't tell about 441.41 i didnt check.
DisableKmRender = 0
DisableKmRenderBoost = 0
EnableDirectFlip = 1
EnableIndependentFlip = (?)
EnablePerformanceMode = 1
