They now use intrusive soldering that solders surface mount and through-hole components at the same time:

The idea behind intrusive soldering, also known as pin-in-paste soldering is simple: solder paste is printed onto or around a through-hole pad, and the through-hole component is passed into reflow with your SMD components. The molten solder paste then fills in the through-hole and attaches the component pin.

What games will not be possible to use on Linux?

Most online games that have anticheat. (yes some work but most don't even if the anticheat could support linux.)

For example, will something like Escape from Tarkov work?

No

And is comparability with older games better or worse than W11?

YMMW. but often linux plays older windows games better than windows.
