Regarding the announcement from November 22nd, 2023. "

• The Emulator & PC requirements

RPCS3 is constantly changing and being updated every day, sometimes several times a day. That being said, some games may run very well one day and not very well the next. In other words, one version of the emulator might run Resistance 2 extremely well and another version may not run Resistance 2 as well as the previous in terms of performance. Furthermore, some games might require somewhat high requirements when it comes to your PC's specifications; CPU, amount of RAM, & GPU (aka Graphics Card). Another way of saying this is, the PS3's system architecture is far more complex than most devices you use day to day and emulating it requires quite a bit of processing power to get playable performance. Most games are playable using hardware from around 2016. However, to get the best performance you'll want to use hardware from around 2018 and beyond. Refer to the Quickstart page on RPCS3's website, though it's gets a bit technical. Or just buy a Steam Deck and setup RPCS3 on it. It's actually really easy to do, though you might have to use the Terminal (there's tutorials on YouTube). When possible, please include the version of RPCS3 used in the run description.

• Rules Implemented

1 - The Unlock FPS patch is prohibited, all games are limited to 30 Frames Per Second. Furthermore, this patch can create instabilities in both the game and the emulator itself. Issues caused by this patch are input detection, animations being too fast, physics oddities or physics completely breaking, etc.

2 - To keep everyone on the same page and playing field, the use of Extended FOV is prohibited for all Resistance games. However, the Extended FOV (Field of Vision) patch works nicely in R:FoM but breaks some stuff in R2 & R3, namely when you ADS (Aim Down Sights).

3 - Use whatever controller works for you. Due the DualShock 3 having shotty support on PC, just use whatever controller works, this includes DualShock 4, DualSense, and even Xbox Controllers. However, controllers that have extra buttons and/or paddles that can be bound to a different button are prohibited as these controllers can create an unfair advantage.

• Run Separation

Runs done on RPCS3 will be in their own category as the Emulator is able to load assets - models, textures, levels, etc - several times faster than original hardware and would be unfair to have them in the same overall category.

Additional note by @SRGTsilent : RPCS3 will also likely never be fully accurate to the on console playing experience for a myriad a reasons, such as the inaccurate rendering of in-game lag when traversing out of bounds.
