I have found a way to get shogun 2 working with special k, with a noticeable performance boost and a fix to latency issues by injecting NVIDIA Reflex into the game.


I had to use global injection as after booting into the game for the first time, each subsequent attempt to start the game would hang 66% of the time, which made it a chore to use. My solution to this is by turning off global injection after it fails to run and turning it on again I’ve had 95% success in getting it to work.

Other important notes: I’m playing in windowed mode to disable legacy flip so that independent: flip works. To get g-sync working from this all you need to do is click on the frame buffer text at the top of the special K window(shift+ctrl+backspace) that matches the size of the screen that you are playing on.

Here is the settings I used:

up to date versions of special k can be found at the discord: https://discord.com/invite/ER4EDBJPTa

Instructions for installing Special k can be found on it's website here:
https://wiki.special-k.info/en/SpecialK/Global

working with version 21.12.8

there is also a support tab on there as well, although I can give some as well.
