FireStick 4K MAX (2° gen.) some advices for Retroarch

I discovered Retroach on FireTV and I was impressed, easy, full of options and a real pleasure to play with emulators using the FireTV (Firestick 4K Max 2nd year 2023) and on a 65-inch TV to boot. I recommend it to everyone obviously. I read several posts and videos to learn how to use it as best as possible, but almost all of them were oriented towards the PC or similar and little towards FireTV, I’m talking mainly about the settings. Therefore I ask anyone who may be using Retroarch on FireTV, what better options do you recommend to make the emulators perform at their best especially N64 and PS1). In fact, the FireTV has decent specifications, MediaTek MT8696T quad-core 2.0 GHz, GPU Imagination GE9215 at 850 MHz…certainly not comparable to a computer
