I wouldn't use it. There's a lot of security issues with it.

If you want more out of your rig, just find a lightweight Linux OS Distro that works with your hardware.

Security would be my main concern with any "customized" version of Windows.

While linux would be an alternative, Nvidia's linux driver causes major fps drop with an Intel cpu. With an FX cpu and it's poor single-threaded performance the fps hit will be worse. With Radeon it's a different story - I have an FX-8320e paired with a Radeon RX 480 running Linux Mint and it performs great. But using an old Nvidia gpu like the GTX 960 w/ linux won't get you anywhere near the fps you get with Windows.

Thanks for your reply :) I've also considered simply switching to Linux, but I've read a lot of negative reviews about Linux and Counter-Strike 2. And since that's my main game, it would probably take me a long time to get used to it and possibly solve problems that lazy users couldn't solve. I've already done a lot of work on the system, and everything's running fine. For example, this is what chat gpt said about it:

Hey! It's great that you're so into tweaking your system - that often gets more out of it than many people think. You've already put a lot of thought into it and apparently already tweaked a lot, so I'll try to give you a realistic assessment right off the bat:

🔧 Your setup at a glance
GPU: GTX 960 4GB → solid midrange classic, but really at its limit for modern games.

CPU: FX-8350 → ancient, many cores, but weak single-core performance - that's what's slowing down CS2.

RAM: 16GB → more than enough, no bottleneck.

FPS in CS2: 80-150 → completely within the system's capabilities, well-optimised!

🧠 The question: Is Atlas OS or another custom OS worth it?
Short answer: In your case - not really, if you've already tweaked a lot.

💡 Why (not)?
✅ What Atlas OS brings:
Removes bloat (telemetry, Cortana, Store, Defender etc.)

Lighter system → less RAM/CPU load in the background

Shorter boot times, fewer background services

❌ What it doesn't bring:
It doesn't magically create FPS → If your Windows 10 is already clean, with a lot of stuff deactivated (Defender, background services, transparency etc.), you might see a difference of 2-5 FPS in CS2 - if at all.

Can cause problems → Some custom OS versions remove so much that Windows updates or some tools/games might cause issues.

🤔 So: Try it or not?
Question Answer
Have you already optimised a lot (registry, services, startup, visual effects etc.)? Yes → little potential with Atlas
If you only play CS2, you don't need Office, Store, Updates, Printer etc.? Yes → then maybe try it
Do you want a stable system that remains safe until you get a new PC? Yes → then stay with your Win 10

📋 Alternatives that might actually bring something:
Update BIOS (if old → can improve stability & boost)

Set Windows Power Plan to "High Performance"

Cleanly reinstall GPU drivers (DDU) and optimise for CS2

Unpark CPU (doesn't work much on FX, but you can still check)

GPU OC (lightly) with MSI Afterburner (only if temps are ok)

Adjust resolution & settings in CS2 - lower is often better on your setup

🧪 Conclusion
If you like to tinker and want to test: Make a backup, install Atlas OS or ReviOS on a second partition or on a separate SSD for testing. Try it out, compare FPS, latency & stability.
But: If you have already done a lot and don't have any problems → It probably won't bring any miracles.

If you want, I can make you a checklist for all meaningful tweaks under Win 10 or go through your current system to see if there is any potential left. Just let me know!

ok thank u for answer! :) ye the rx 480 is way better.

No. It's not even that different than Linus Titus tool.

Sadly ChatGPT too.

High performance plan is not the best plan in Windows. Ultimate is High performance but makes HDDs to never stop spinning.
Here is what could make a difference: if processor performance time check interval (a hidden setting in power plans) is increased then the system will make less check so you will have slightly more processing power for the rest tasks but it also requires more time to change cores' different power stages (frequency) and from parked to unparked state or the opposite way.

You can run the same amount of services as if you're in safe mode with additional of the essential ones that allows you to have a normally working desktop. Sadly I still don't have the complete list.

Nobody tells you to set IRQs of the GPU to the highest priority. Or play around the reserved amount of CPU time for background tasks.

See, the list is long.
Also, disable FSR in CS2 and play on lower res instead.
The pooling rate of your mice and keyboard also can affect on performance of the CPU.

Hey, thanks for the tips. Yes, I worked with Chris Titus' tool. To be honest, I use Ultimate Power Plan but it's been a little optimized. For me, it works great. I also disabled memory compression and process mitigation in the registry. I tweaked my latency, input latency - keyboard and mouse , the latency itself, and BCD. I also optimized the CPU priority, even if it's minimal with my prehistoric CPU. I have set Counter Strike 2 in the registry so that the priority is high.

in cs2 i play on lowest settings and lower res. so, my game works good for me, i was just wondering if some custom os can do more, but it doesnt look like that xd

but much thanks for the answer!!!!!

Id keep using what you have, maybe even try rufus and win 11 tpm bypass on a small test partition see if cs fps goes down
