On a fresh install I get recommended frames of 60 on my rig and it does indeed look smooth. Occupancy seems to shade over 100 at start of races but soon settles down and goes as low as about 50% on some tracks... rain does push it up a bit.
With my updated 2003 cars and anim.wad I get recommendations of about 53-55 fps.
I recently cleaned out my registry and re-installed my sblive plus drivers and now things seem much faster.
I just installed the absolutely fabu-tastic-agorical 1995 mod (love those pointy cars and fat slicks !) and the cars.wad is about 85 meg so I expected to get a huge hit in frames..... much to my amazement and delight it get a solid 56-57 fps.....
sorry to sound like a brag-ass but it really made me smile and I like to know if others are having similar results...... btw the Omega drivers I installed over the top of the original Cat3.5 drivers maybe the difference ?
