macOS Big Sur RX580 ioquake3 runs in "power save mode"

[lyons88]

IOQuake3 isn't triggering the higher clocks of my RX580 in macOS Big Sur( Intel ) The RX580 stays @300Mhz Core and Memory Clocks when running the game.

Can you say what framerate you're getting? (Use cg_drawfps to display the framerate in-game)

In the time demo I'm getting about 335 FPS with s_initsound 0.

I have a utility( OpenGL Driver Monitor ) to monitor the clock rates for the card while I run the demo or play the game and they never move from 300Mhz.

These clocks should be ramping up to the max( 1340Mhz Core/ 2000Mhz Memory ) when we call the OpneGL context( launch the game ).

This only occurs if the game incurs significant enough load on the GPU. Lightweight GPU workloads intentionally don't cause clocks to raise to the maximum value to save power. Otherwise, GPU clocks would raise to the maximum value as soon as you start a web browser, as they all use hardware acceleration now :slightly_smiling_face:

Modern high-end GPUs can easily run Quake 3 at 333 FPS while staying on their boot clocks (or in an intermediate state).

Looks like everything is working as best as it can to the GPU driver. 300+ FPS sounds great!

Cranking up the graphics settings resolves the issue.
