He he.......just missed those lines 8-)

I've never used ORBX stuff before so I thought I'd give it a go on my low end PC. I say "Low end", perhaps it's better to describe it as old...... Single athlon 3000+ cpu with a nvidia 7300gt 256 graphics card, 3 gig ram.
I didn't hold out much hope

Pleasantly surprised though, I installed the freebie and had a go.........18-20 fps quite smooth and worthwhile. I did notice that the extra eye candy wasn't present, no tufts of grass, people cars etc.
It transpires that the FTXA_ORBXLIB (Library) file is needed also, a separate download . This is downloadable from ORBX patch webpage. (probably common knowledge to everyone except me

)
With that installed this scenery looks the mutts nuts

. Getting between 15 and 20 FPS and quite smooth, so even on an old machine it runs reasonably well.......So thanks for the heads up mfaulisi.
