FPS Increase - Set Affinity for Core 0

[DA * Butthole]

Why do I never hear about this in guides that recommend fps solutions for CS:GO? I used it and instantly my shots were registering better.

(Edit: You have to do this every time you open CS:GO.)

Open CS:GO, then open task manager. Right click CSGO.exe and left click "go to details", then find CSGO.exe and right click again. Left click "set affinity", then uncheck Core 0.

Core 0 handles all the background stuff on your computer, which means that when there is back-and-forth gunfire, molotovs and smokes, or awkward player movement on one or both sides, then Core 0 can become overburdened. On budget computers, it is essential to have it unchecked.

holy heck, this shi...rt has to be pinned on top
i did it a few month ago, but forgot to redo that when i got my new pc

How do you figure that out? Where do the benchmarks come from?

Also, I made this post elsewhere and apparently it has to be done each time you open CSGO. Do you have that issue?

I use a script to start Steam with affinity set for the CPU cores I want enabled. I don't have to manually intervene that way.

How is that done?

Now it helps, for me anyway, to also set core 2 off. Benchmarks show that cores 0+2 off is best for my PC.

I lost 70 fps doing this :O

Is there any way to save this? It's annoying to alway redo this.

What CPU?

Any two of the quad core.

I have played too many games without it to care at this point, but apparently you can create a script to do it. I dont know how though.

Just tried this out. Didn't noticed a difference but if it's good for my PC then I'm okay. Thank you for the guide Didnt got any FPS drops too

anyway to save it? hate having to do it everytime

Which background processes are you running which only run on core 0?
Your background processes should run on any core.
You can confirm this by closing all your programs, opening Resource Monitor and checking the activity on each core. If you're only seeing activity on core 0, then you might have a bigger problem than cs:go fps.

You don't need to set affinities each time you launch. They can be specified via a shortcut or batchfile, launching your process via cmd.exe. However restricting process affinities is much more likely to make things worse, rather than better.

I agree that it should work as you describe but my testing showed an increase in FPS when some cores are blocked from use by Steam/CSGO. But this may just be my special case.

YMMV

How many cores do you have?
Do you have multi-core rendering enabled?
Can you post an image of your Resource Monitor | CPU please?

i7-4790k

yes multicore is enabled

At what point for the screenshot? While doing a benchmark with the FPS map maybe?

Your processor has 4 cores.
CS:GO runs 67 threads.
It's difficult to see how only giving cs:go access to 3 of your cores can do anything other than slow things down.

I'm interested in the screenshot, because I want to see the activity you're getting on each core.

You probably want to see what happens with all cores enabled, right?

Your peak usage on any core is 88%, so that case is throttled by GPU.

See the update above

GPU is a 1070 Ti overclocked a bit

I mentioned it might be PC specific and testing is required

And YMMV.

It looks like csgo isn't generating enough work for 3 of your cores.

What happens if you run with
-threads 8?

Also try dropping the resolution down to minimum, to remove the GPU bottleneck.
