Everything fine on my side here . very smooth .
Seegert `s Monza version ( 39MB ) serves me constant 59-60 fps on – and offline.
Vsync on or off doesn’t make any difference .
Monaco Rocks 2 with tunnel and horizon highres stuff , as well serves me 59-60fps. ( offline 1 car test mode ).
Main fps killers I do know
< Anti Aliasing : e.c. in my case x4 is max
< Z Buffer if set to 1 inside GPL `s core.ini
<level of detailed set to 100% inside GPL

Core.ini Direct3D7 settings : attention on Z buffer
[ Direct3D7 ]
D3DDevice=0
TossHighestMip= 0 ; 0 gives best, sharpest image / 1 for lower end cards (image will be blurry)
DoubleMirrorResWidth=1 ; 1 gives best mirror resolution / 0 lower mirror res for lower end cards
DoubleMirrorResHeight=1 ; 1 gives best mirror resolution / 0 lower mirror res for lower end cards
DirectMirrorRendering=1 ; 1.....Use 0 only for problems with image location (i.e. it’s in the corner of the screen)
DisableZBuffer=0 ; If you use 1, disabling the Z buffer will reduce frame rate by 60% according to the readme.
AlphaThreshold=1 ; 1 for better cards / 240 for lower end cards (trees look moth eaten)
TransparentMipsDrawOrder=1 ; 1 for best image / 0 for lower end cards (trees look moth eaten)
TrilinearFiltering=1 ; 1 for best image / 0 for lower end cards (non-single pass filtering, blurrier image)
AnisotropicFiltering=16 ; 16.....higher for best image (1 (0 level), 2 (1 level), 4 (2 level), 8 (3 level), 16 (4 level filtering)), enabled in newer cards only
LODBias=-50 ; .....Try 0 (blurrier), -50 (sharper), -100 (far textures tend to speckle). Aim for a setting that looks sharp without speckling.
Maybe some useful information in that above.
