I tested the same install on TF530 and TF536 (MMULib + FastRom installed).

On the TF536, Formula One Grand Prix plays like on slow-mo. Don't get me wrong... it does get accelerated, the screen updates are fluent.
But it feels as if the game's sense of time is skewed somehow to make everything move slower.

Can anyone confirm my observation?
Just start a race, hop in one of the computer cars and follow it around.

I've just tested this on the 536 r2b and the 330 r3. I don't notice the issue described.

RC50C CPU in both 536 and 330, running from the same SD card/image.

I start the race and press the up arrow key to change car. Everything looks smooth and timing feels correct/realistic on both machines. Perhaps slightly smoother/better rendering on the CD32 but it's hard for me to tell objectively and the last time I played this game was probably 1992.

Test your CIA timing in Amiga test kit and DiagROM.

Btw I only tested PAL machines

Check the clock app works ok too

I think I resolved it to a PEBCAK. :oops:
When I ran it on the TF536, F1GPEd had patched the executable to an unrealistic framerate. Apparently there are some hardcoded assumptions in F1GP about how fast it can render and how much wallclock time that will take. If you feed F1GPEd with a too high framerate, the game thinks it runs at a higher framerate than it actually does and thus everything will feel like in slowmo.

SysTest attested good health to my CIAs, the clock app runs at normal speed.
