Most of the chips in a smartphone are made by Qualcomm, both processors and peripheral chips like 5G modem, LTE modem, WiFi, and Bluetooth. Qualcomm chips require proprietary binary blobs to function, and usually only have a support lifetime of about 2 years. They also only supply those blobs to the manufacturer of the device.

To be clear, these are game problems, not NVDIA GPU problems. Some games only work on Windows and need to use a translation wrapper, which has overhead.
