I've recently switched from being a long-time Windows user to trying out Linux, specifically Kubuntu. I set up an old gaming laptop with specifications including an Nvidia Geforce GTX 1650, 8GB of DDR4 RAM, and an Intel Core i5-1030H, and I've been testing the performance of CS2 through Steam. While I can get about 130 FPS on Windows with mid to high graphic settings, on Linux, I'm struggling to reach even 30 FPS, even with the settings dialed down to the lowest. I've tried various startup parameters, different Proton versions, and switched between Nvidia drivers and the open-source driver, but the performance is still disappointing and often results in crashes after a few minutes. I want to know if it's normal for CS2 to perform so poorly on Linux and if there's anything I might have overlooked to improve the situation.

Switching to dual boot was smart! You'll generally see a performance hit with integrated graphics compared to dedicated GPU setups, especially on older laptops. Just make sure that your Nvidia drivers are the most effective version for your setup, and your parameters are correctly configured. Also, consider testing with a lighter Linux distro for potentially better performance.
It sounds like your laptop might not be using the dedicated GPU properly, which is common with Nvidia setups on Linux due to how graphics switching can be set up. Have you looked into Nvidia Prime? It can help with better GPU management. Also, increasing your swap file size is a good call, as that can affect performance too. If you're serious about gaming on Linux, switching to an AMD setup down the line could save you headaches in the future!
I can relate! When I first moved to Linux, I was surprised by the performance drops, especially on older hardware. Keep your drivers updated and maybe explore different Vulkan settings. You might also find community forums helpful for tips on optimizing your specific hardware.
