Game Lags Other Applications

[Instacake]

So I’ve been having some lagging/frame issues when I tab out of monster hunter. Basically applications like discord and OBS get some sort of input lag or frame drops when performing actions.

PC Specs:
i7-7700k
GTX 1080ti
32 GB 3600 RAM
ASUS strix motherboard
Running SSDs
Dual ASUS monitors: (1) 1440 and (1) 1080

I see the issue the most when trying to stream. I’m able to play at a constant 60-70 frames on 1440 while streaming but for some reason OBS and the stream on twitch stutter heavily. If I tab out and use discord, scrolling through chat is lagged.

Things I’ve tried:

1. Turning off one cpu core (core 7) for MH World. Maybe I did it wrong? But still had issues.

2. Unplugging my second monitor and only running my main. Still had issues.

I’ve modified a few other setting to no avail. I’m pretty convinced it’s just something with the game because it’s the only game I have this issue with. Any input is appreciated, I’m sure others might be having the same issue.

Try and use the Special K mod: https://steamcommunity.com/app/582010/discussions/3/1745594817439431537/

The game have a thread that by itself stands for like 25% of the CPU usage of the game, and it's completely irrelevant and constantly performs context switches between kernel and user mode.

The option to kill that thread is enabled by default, so it should just be about extracting the contents of the archive to the game folder and launch the game and see if anything changes.

Thanks Aemony, I'm barely getting to try this since it's the weekend. I'll let you know how it turns out.
