Cannot complete "Don Peyote" - with TTDISA + Silent's ASI and v1.0 (12-9-2014) downgrader

[SpinaroX]

As described above, trying to complete "Don Peyote" for the bazillionth time using the above modifications.
The game freezes for a split second and crashes upon CJ, Kent Paul and Maccer driving closer to Las Venturas. Tried frame-limiting, didn't work.
The only successful attempt was by approaching LV from a different direction but since then I had lost progress due to more instability (yeah yeah "don't use mods" etc I know).
Has anyone experienced this kind of problem? Can anyone help out at all, please? Doing my head in at the moment... Would appreciate anything

Ok so I passed it. I suspect the problem was due to my enhanced draw distance in my timecyc.dat - took it down from 3000 to 2000. Enabled frame limiter for the period of the mission, and approached the end point at Caligula's from the north end of LV.
