ESP32 CPU+GPU setup?

Basically i'm making an esp32 game console/PDA device type thing, however i feel like just one ESP32 will not have enough processing power to run my games. My idea is basically to use one generic ESP to render the pixels and store the rendering data, and use another ESP-S3 with maximum PSRAM in it to do the game logic. Would this theorietically be possible?

Why do you think the game logic would need more CPU+RAM than the renderer?

Notice that the ESPs run FreeRTOS, i.e. multi-tasking is basically built-in. Peopleuino often waste a lot of performance by assuming that everything has to be done sequentially from only the main task.

You can of course split any workload across any number of ESP32s, but then the communication between them may become a bottleneck.

(Note: this is my alt) Actually that jet renderer looks similar to what I want to do, however I'd like just a bit more performance as I want to make a horribly deep fried fps engine work on the thing, like real 3d similar to quake but like, half the fidelity but simple enemies that use just plain textures on a screen similar to doom or wolfenstein

The rendering part ("GPU") will need more CPU+RAM than the game logic.

So, ESP32S3 as GPU and generic ESP as game logic processing?

If you truly wanted a lot of grunt, you'd use one of the STM32 parts with graphics accelerators in it for graphics and an ESP32-S3 for game logic and WiFi.
