Not for me:

Actually big maps (like a huge pfs) lag much less than those from Tmuf. Here in TM2 i have no lags with anisotropic 8x filtering, on tmuf I do (yep my pc is only 2 years old and already obsolete). Plus TM2 looks much better IMO.

for me it's vice versa |: on TMUF on high settings I have ~30-50 fps, when in maniaplanet with the lowest settings possible (lightmaps off^^) I have maximum 35, usually ~20-25. and obviously TMUF looks better than Canyon.
