I finally found out how to avoid the problems I have had with
GPL and my TNT.
PROBLEM
With TNT on 378MHz Celeron, GPL is impossible to drive consistently.
I set the graphics options to get around 36fps but even though the
framerate dsiplay shows 36 most of the time, it's obvious that the
framerate is not consistent. I was lucky if I could get more than
two laps into a race without spinning off.
SOLUTION
Last night I gave up on my TNT and switched it for the Banshee in
my other machine. With exactly the same graphics settings as the
TNT, the Banshee gave a solid 35.xx framerate from seconds after
the start.
With the banshee and a consistent framerate it was much easier to
control and it didn't take long to improve my lap time. More to
the point, it was MUCH MORE FUN!! I completed my first race, with
a lot of close racing with Surtees (yes I'm still down towards the
rear of the grid).
I wonder how many people using TNT think they are getting good
framerates, but then say that GPL is too difficult. If they
just switched to a supported card they might find it a completely
different sim.
