This gave me a great fps boost and removed stuttering.
Guide to Boost FPS and Remove Stuttering
What to Do
- First, copy and paste the following lines into your Engine.ini which is usually located at C:\Users\yourusername\AppData\Local\Insurgency\Saved\Config\WindowsClient:
Save the document after you have added these lines.
- Next, right click Insurgency Sandstorm in steam and select properties. Copy and paste the following launch commands (remove the ones you already have if you have any):
-USEALLAVAILABLECORES -NoGlobalInvalidation -dx12 -malloc=tbbmalloc/system -NOTEXTURESTREAMING
After you’ve added these launch commands, start your game and go into your settings and turn off Texture Streaming Pool. Exit the game, remove the launch command “-NOTEXTURESTREAMING” and launch the game again without this command.
- The textures should look horrible and if not, try turning Texture Streaming Pool to high and then to off again (it should look like ♥♥♥♥). Now open the console command in game by pressing the tilde key | or F5, if nothing happens press shift + alt and try again.
(When the console opens, you can press shift + alt again to return to normal typing.)
After the console pops up, type r.streaming.poolsize -1 and press enter. Boom, your textures are back and it should now be amazingly smooth and give you a big fps boost with basically no graphical loss.
Also keep in mind that you will have to enter the console command r.streaming.poolsize -1 every time you start the game, and every time you change the settings.
