The MAGIC FIX For Better Performance in DCS World 2.9!

Today I wanted to highlight a magic bullet for increasing your performance in DCS World when it comes to load times and that lowest 99th percentile dip in your FPS.

Lately I have been extremely frustrated with DCS World 2.9 and its performance and more specifically the consistency of its performance.

I recently went a bit overboard with my home cockpit refresh and built an entirely new rig for playing DCS World and Video Editing.

This PC is a monster with an intel i9-14900K, RTX 4090, 64 GB of Ram… the works.

Now normally you’d think that this would translate to a huge increase in DCS World’s performance… and it did…. With the huge caveat of much higher highs when it came to FPS, and much lower lows in the 99th percentile… and weirdly long load times for missions and then textures once I was in the cockpit.

And on top of this it was extremely inconsistent, sometimes I would hop in the cockpit on a simple empty mission with no other units around and it would be a stuttery, screen tearing mess that was nearly unplayable…

Then on my next play session I would fly in a DCS Multiplayer server with 50 other pilots and get fantastic performance I could have only dreamed about a few years ago.

This inconsistency and huge ups and downs in FPS had me ready to tear my hair out as I tried every combination of graphics settings possible trying to fix this frustrating inconsistency!

After trying everything possible within DCS World’s settings and options I decided to look outside of the realm of graphics settings and look deeper into issues of inconsistent performance of applications across the board in windows 11.

This is where I finally found the culprit… Windows Defender… As usual… and I feel really stupid that I hadn’t caught this earlier.

So let's dive into how we can keep Windows Defender to stay the hell away from DCS World and all other apps you use to enhance your DCS experience!
