Yup. I am running it on older hardware and get single digit frame rates. On
some courses, I will get 5 or more which is passable. On others, I get less
and the game can be almost uncontrollable. For the same reason, I cannot run
flightgear. But at least, ppracer remains playable.
The new version is doing more. Shadowing, haze, etc. These features can be
turned off but I did not get better frame rates by doing so. While the
shadowing could make such animation a bit more real, this implementation is
marginal. There comes a tradeoff between algorithmic features and performance
and thar's the rub. I would rejoice with a 75fps display :-)
