The owner, testing on a 165 Hz display: ~60 fps natively, but with frame generation at 8x the game fell to ~10 fps while the counter showed ~60.

Each game frame's made frames are shown at the display's refreshes, so at m x the game runs at most refresh / m: 8x on 165 Hz holds it to ~20 fps. With 7 frames made on the GPU for each of its own at 1440p, it fell to ~10. The log agrees: most made frames were shown 12-17 ms apart, and over half were late.

A fixed multiplier is now capped at refresh / 30 (at least 2), so the game is never held under 30 fps to fill the display:

display	most
60 Hz	2x
144 Hz	4x
165 Hz	5x
240 Hz	8x

The cap is logged once when it applies. Auto is unchanged. tests/test_framegen_auto.py checks the caps (passes locally).

Draft: it still needs an in-game check at 8x on the 165 Hz display, which waits until the owner's test session is over.

Superseded by the frame generation rework (the PR for branch fix/framegen-native-kept): it caps a fixed multiplier at what the display can show and never lets the display thread hold the game back, rather than only keeping the game above 30 fps.
