Your system information

• System information from steam
• Have you checked for system updates?: [Yes]

Please describe your issue in as much detail as possible:

Now if you change beta version CS2 to csgo_legacy and you no have SSE4.2 support in you CPU, you no can start csgo_legacy from steam UI button play. If you set this launch option

%command% 2> log

And start game (game not started) you see in the log file

Launcher Error: A CPU that supports the SSE4.2 processor feature is required.

But it fake information, because for csgo_legacy no need SSE4.2 Okey, now set this command launch options

LD_LIBRARY_PATH=./bin/linux64 ./csgo_linux64 -steam && %command%

Now csgo_legacy started fine from Steam UI play button. Find in internet public servers for csgo_legacy and play :)

Maybe make it so that in case of switching to csgo_legacy the launcher does not block the launch of the game. And you don't have to do such things. I understand that the previous version of the game is no longer supported and there is no particular point in writing about it here, but I am not asking to support csgo_legacy, I am simply asking not to break its work. Thank you. Bye bye ::)
