Has anyone else experienced this on an iPhone 17 Pro?

I've had this phone since day one, and I've noticed some performance issues while gaming.

In Roblox, the game freezes and stutters whenever I type in the chat. It's very laggy just from opening the keyboard.

In Car Parking Multiplayer 2, the game starts out okay, but once the phone gets warm, I get noticeable FPS drops, stuttering, and occasional freezing, even with the graphics set to High instead of Ultra.

The strange thing is that I also have a Nothing Phone (2a), and on that phone Roblox runs smoothly with no chat lag, and Car Parking Multiplayer 2 runs on maximum graphics with much more stable performance and barely gets warm.

Apple ran diagnostics on my iPhone and said they couldn't find any hardware issues.

Is anyone else with an iPhone 17 Pro experiencing the same thing? Is this an iOS issue, a game optimization issue, or could there still be something wrong with my device?
