RCPS3 configuration: some missing options in my emulator version?

Hi

i noticed that there are a couple of configuration on my RCPS3 version (I'm using the latest released version) that aren't like I can see in some youtube videos:

1) CPU --> TXT Instructions is always disabled/deactivated.  Why? How can I activate it, if necessary?  See this: https://i.postimg.cc/FH44gpmz/Cattura4.png


2) Advanced --> Firmware Settings section is missing.  In a lot of youtube videos this option is present. See this: https://i.postimg.cc/HxJRC8HF/Cattura5.png

thanks!

When TSX is disabled it means you don't have hardware support for it
Firmware Settings is not required anymore, HLE and LLE is done by using both library selection groupboxes

thanks!

just another couple of important questions:

1) when i upload my logfile in Discord channel, everytime the BOT says: Multithreaded RSX is enabled. Is it better, by default, to disable this option? In some guide on youtube i found that it is better to enable it. But others guide say that it is better to disable it...

2) my monitor is a fullhd monitor. In order to have a good resolution without slowdowsn, is it better to set by default RESOLUTION SCALE = Default? Currently my Default is 300%. Here my default config:

Is it ok? Or is it better to change Resolution Scale = Default (100%) ? Here my pc specs:
Case Silverstone SST-RVZ03
CPU AMD Ryzen 3700X
Motherboard Gigabyte X570 I AORUS PRO WIFI
RAM 2 x 8 GB Kingston HyperX Predator 3200-16
GPU RTX 2060 Super

thank you
