Don I followed you instruction below for OpenGL. Here is what I found in
"Daytona night".... Alone in testing turns 1&3 = 90-94fps 2&3= 70-75fps.
I guess the lower fps in 2&3 as the stands came into view?
In a 21car race at the back of the pack at start 30-35fps after moving into
the start flag up to 45-49fps & finally racing several laps consistantly in
the
50fps depending on how many cars around me. Car draw 8 front 4 back!
I will test the same with D3d later as this is what I was using but it seems
OpenGL is the better of the 2?...Thanx Again.. Thom_j.

| Open GL does indeed automatically take advantage of the hardware TnL.
| My Open GL settings are as follows:
|
| Use desktop color depth ( mine is 16 bit)
| Buffer flipping mode: Auto Select
| Vertical Synch: Always Off
| FSAA: No antialiasing
|
| In the performance and capability options:
|
| Enable buffer region extension: Checked
| Allow dual planes extension to use local video memory: Checked
| Use fast linear-mipmaplinear-filtering : Checked
| All the rest unchecked.
|
| I also run in 1024x768.
|
| No idea about about the aliasing issue with D3d, I have tried it on all
| settings, don't really see a difference on the screen or in framerates.
