Things that affect input lag:
Your monitor settings.
Your monitor cable.
Your OS settings/registry/ect. Process Lasso and Project Mercury might help especially for Ryzen CCX performance.
Your application settings: disable fullscreen optimization or aero for win7.
I also just found this amazing reg mod that boosted my frame delivery performance by 25-50%. If you have AMD gpu I definitely recommend downloading Radeon Mod. It is akin to Nvidia Profile Inspector.
"Here's the (ocasionally) updated pastebin version of all the tweaks i found that do something on AMD GPUs. AMD GPU Performance REG for 19.1.1+
I got banned from google+ for posting links to this as .reg files, which is ridiculous btw. It's ok, G+ is dead anyway.
(UPDATED 14/03/2019 for bugfixes. Should work now.)
I tested this with a RX 580 V1 MSI OCed to 1425core 2250mem 50% power limit and with disabling the 300mhz memory P0 state in overdriveNTool, great performance. I also added some DVRanalytics keys to disable in case you enabled AMD User Experience improvement program. Driver latest 19.3.2 tested on Windows 10 1809 October Update, AMD Ryzen 5 2600X, 16gb of RAM PC."
Theres also this other radeon reg file that you can try out as well. https://www.reddit.com/r/Amd/comment...m_medium=web2x
Does anyone know of any other REGEDIT optimization that I can possibly do? Especially on the MMCSS?
Whenever someone is suggesting a change to \Games they always say: "In the same Registry hive as the above tweak, you can also change the priority of Games. To implement this tweak, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\G ames and change the following registry values:
“GPU Priority” change its values to 8 for gaming.
“Priority” set to 6 for gaming."
However on the microsoft website it says:
"Priority REG_DWORD The task priority. The range of values is 1 (low) to 8 (high).For tasks with a Scheduling Category of High, this value is always treated as 2."
Oh last but not least, MSI Utility. You can configure MSI line interupts manually but MSI utility just so much more convenient. https://forums.guru3d.com/threads/wi...rrupts.378044/
The utility was updated recently and now you can add priorities towards each device as well, however I just don't know which settings are the most beneficial yet.
Also there still seems to be some performance increase by disabling HPET for ryzen systems(in BIOS).
If you know any more performance tweaks please don't be shy. Especially registry tweaks.
