Hello there 1- It really depends on your build, distro and drivers being used. Some benchmarks show Ray tracing causes performance drop compared to Windows.

2- There are mod managers here and there but, honestly I don’t mod so I don’t know anything about it.

3- If a program doesn’t have Linux version, there might be Linux alternative. Those alternatives sometimes might not be on par with their counterparts though. Adobe products are one bit example.

4- Applications developed with .NET may be built on Linux through Mono framework, as long as they are developed as portable. For native Windows programs, there is a compatibility layer named WINE, but it won’t guarantee that every program will work. It may support games as well, but for games Proton is more preferred. Proton is Valve’s official tool anyway.

5- Distributions’ package managers will manage updates, either application updates or system updates. Most distros will also notify users about updates, however installing them is up to user’s decision. Universal package managers like Flatpak are responsible their own updates.

6- Linux is way more secure than Windows for being what it is. Being an open source does not inherently mean that it’s secure. But open source softwares are generally peer reviewed by public and they are often recommended fixes thus if there is any vulnerability, it’s fixed more quickly. Antiviruses are not needed, not because there is not Linux viruses though. There is ClamAV anti-virus, also there are proprietary AV applications, if you still need. AV’s are mostly ineffective in today’s technology.

7- AMD drivers, for example way more reliable than their Windows ones. Nvidia also made a lot of progress in recent years, so yes. There might be still some issues, lack of features.

8- No, it cannot.

9- For a beginner, Linux Mint is and always has been best choice for start, in my opinion.

Not everyone has enough knowledge to differentiate fake posts from real posts. Some people come here to learn new things, some others come to ask questions, to learn troubleshooting. You make one claim and refuse elaborate further. Instead, you insult people who ask for explanation. Understood, you are a genius which can see things and everybody else is pathetic losers.

“It’s fake because I say so” is anything but a valid argument. This comment is no better than those fake posts you are mentioning.

OK my bad. It wasn’t Steam statistics, but another statistics for overall Linux desktop usageon statcounter

No, I am so lazy to find source right now but it was a steam statistics too.

It was around 5%. Ban on online games might have affected.

Windows 10 ending support just means that you won’t get updates. Your Windows 10 installation won’t vanish instantly. Keeping Windows is when you change your mind or have a problem with your Linux installation, to have a backup system.

That’s a good. You may still keep Windows on the side to use just in case. And you may use Linux all the time until you get really used to it. Then you may totally remove it sometime. I advise you to keep it until you’re really sure.

Depends on your needs. If you use any proprietary production tools like Photoshop, you may still need to keep Windows on the side. As for myself, unless the user really gets used to Linux, gains some experience, I do not advise to switch to Linux fully. I’ve seen so many people who did this and returned back to Windows.
