What to Do

1. 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:

[TextureStreaming]
BoostPlayerTextures=1.0
AllowStreamingLightmaps=False
r.Streaming.DropMips=0
r.Streaming.LimitPoolSizeToVRAM=0
r.Streaming.MipBias=0
r.Streaming.UseAllMips=1
r.Streaming.UseMaterialData=1
r.Streaming.UseNewMetrics=1
r.Streaming.UsePerTextureBias=1

Save the document after you have added these lines.

2. 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.
