Three bugs on Low PC

[Lavinian]

OK, I´m instaled VDrift on PC with
AMD Athlon XP 2200+
768 MB RAM
and Geforce FX5200 (only OpenGL 1.4, so forgot about Cg )

This game won´t run normally, but I´m used NaN bulid and works with 60fps on Very Low settings and 11fps with Very High settings, but...
these problems appears on all settings

1) In select menu cars doesn´t have roof, in game looks normal
2) Smoke looks kinda screwed, like this http://www.youtube.com/watch?v=XJBd7fqRb8Q and sometimes doesn´t see anything
3) Cars looks like toys and have too bright colour (like this video)

I´m don´t know where is problem because I´m can run Battlefield 2, Gothic 3 or Racer with no_cg which is much demandier than this and doesn´t have any problem with smoke or bright colours.
It´s posible get rid these bugs with any Low PC?

You are running 2010-06-30 version?

The non shader mode is a fallback, has a lower priority. The smoke issue has been fixed by disabling it in non shader mode. The roof is a glass blending issue I guess. Unfortunately we only have access to a limited number of hardware components to identify and fix such issues.

Have you tried to run previous releases?(2009)
