pi5 games running slow

[sandatomo]

greetings,

I got a brand new raspberry Pi 8GB model, I bought a Canakit starter pack, comes with power supply, case, fan and a Samsung 128GB micro sd card.

I set it up with recalbox and put a couple of games in it.

Everything was working like a charm, I have transfered a couple of psx games over FTP, however out of the blue the game started to run super slow, I close it and try a different one with the same result, is super slow which makes it unplayable.

I tried looking in the forum and over the internet in general, I do see advice for other models of raspberry, tried applying some of those changes, but sadly no luck.

On another topic, intermittently I see a "wifi" controller on the top left on my screen, I'm not sure why is that and it shows again out of the blue, sometimes appears and sometimes it does not, weird ...

Please find attached a video showing the problem with one of the out of the box <Ports> game:

details for my current setup:

TV - Samsung 4K 55" (I can't remember the exact model but I can elaborate on it as needed.)
Board model: Raspberry PI5 - 8GB model
Recalbox version (build) : Recalbox 9.2 Pulsar - Experimental
Hardware:

• Storage: Micro SD Samsung 128GB
• Power Supply: Canakit 45W
• Case: Canakit black case
• Xbox 360 controller via xbox 360 wireless adapter plugged in USB port 2.0

Thank you for reading, if you need logs, configs or any other data I can provide w/o a problem, I'm feeling super frustrated b/c I bought this kit with a lot of effort but as of know I'm thinking of sending back the product to Amazon.

Thank you for reading

Hello,

Your version is experimental. I suggest you force your resolution in 1080p on advanced settings.
It will be solved for stable version

@Magaki hello and thanks for your help, yes you are right setting a fix lower resolution works! and actually doing a little bit of experimentation I found a sweet spot of 2560*1440, it works perfectly.

Again, thanks for the assistance

More than 1080p will not be necessary for retrogaming
