Your GPU is very weak, and because it was a budget card back in the day it doesn't have support for a "new" technology called Vulkan which is an alternative to OpenGL.

Vulkan is used by Proton (you can think of it as a Windows emulator, even though it's not exactly an emulator) to convert DirectX calls to something native. Without Vulkan Proton needs to convert DirectX to OpenGL which loses a lot more performance, and in the case of newer games (ones that use DirectX 12) it's not possible.

So it really depends on what games you want to play, realistically I don't think you're playing anything with DirectX12 because those games are all newer than your card, so I don't think your GPU would support them even in Windows.

I would say give it a go in a separate partition/disk/thumb drive and see how it goes. I don't think the experience of gaming will be good for you, but I can't imagine the rest of the PC has good specs if that's the GPU, so day to day might be a lot more comfortable on Linux without windows hogging down resources.

This card requires legacy drivers. Getting this to work is going to be a pain and a half in the rear. I've done it before.

Basically, what you need to do is this:

• During OS installation it will install the modern GPU driver, which will not work with that GPU
• Once installed, boot the PC. You will very briefly see an error message during boot that the GPU isn't supported by the driver.
• Now you first need to unload the current driver kernel module.
• Then unstall the current driver package in your package manager.
• Install the 470 legacy driver from the package manager
• Load the legacy kernel module
• Reboot and hope it all works.

Google how to do each of these steps, since they are a bit too complicated to get into it here, also they are dependant on the Linux distro you chose.

Btw: you will be losing frames. Support for legacy Nvidia GPUs isn't great at all.

My suggestion is to use a beginner distro with easy dual boot options. Linux Mint comes to mind. Get that going and try it out. If it works for you, you can then move on to ditching your Windows install and/or using a more advanced distro.

Unless you're more of a "dive into the deep end" sort. If that's the case, grab Fedora Workstation and make sure to enable the proprietary software repositories. Fedora is stable, and the desktop will be a reminder that this isn't Windows and it won't act like it. From there, you can find help all over the place, from Fedora's documentation and forums to simple internet searches.

Linux Mint offers the option to install it as a secondary operating system so if something doesn't work on Linux, you can just switch

Dual boot, don't switch.

You'll likely lose some frames by switching to Linux but not much. It really depends on the games you are playing. Check ProtonDB for some of them

Depends on the game tbh. What do you like to play?

If I don't game, then Linux is worth for my config?

Are you not going to list the games that you want to play? If so, then just head over to www.protondb.com and make sure they are playable.

Why do you want to switch to Linux in the first place ?

Personally, I wanted to be in absolute control of my PC. I am a professional book cover illustrator and after ~30 years of using Adobe Photohop and Illustrator, I blindly went all in on Linux. I found my way, differently than I imagined, but happier than ever.

If you have the will, you'll find your way.

You should definitely give it a shot! Due to proton, you should be able to play most, if not all, of the games you play om windows (unless they have obnoxious anticheats). A good resource for checking game compatibility on linux is ProtonDB. In terms of performance, there will almost certainly be a slight impact, but in my experience (with an admitingly far more powerful gpu) it really is minimal. And if it really doesn't work out, you can always go back to windows.

Can I be able to play the games that Windows supported without losing frames?

It depends on which games in particular, some games actually have higher framerates in linux, but you will likely lose a couple frames, not much though. If you have your games in Steam it's pretty easy to just enable Proton to play everything, you can check protondb.com to see how well each game works and possible performance options. You will likely need to install the nvidia linux graphics driver for good performance on your nvidia card, most linux distros default to the open source nouveau driver, which doesn't perform as well, but there are distros that include the nvidia driver on install like Pop!_OS and Mint

Nobora or popOs or any others?

It sounds like the best option would be a dual boot, Linux for everything except games and when you want to play just boot into Windows. If you do this i would strongly suggest a two HD set up, one for windows and one for Linux, for two reasons, if you don't like Linux then you still have the original windows setup, two Windows will at one moment wipe the dual boot grub and you'll 'lose' the Linux startup, unless you have one OS per Hard Disk. I don't game anymore. Like you I also have an old card Gtx760 🤣🤣

tl;dr: for this GPU better dualboot and use Windows for the games.

What kind of pc do you have? Is it a pre-built, a laptop, or is it a custom build desktop?

Also, what kind of games are you planning on playing?
