I didn't mean to "flame" the authors of the software but i do take notice of the minimum & recommented specifications of machine required to run the game(s) prior to purchase.
Regarding the MX440 (ASUS 8170 DDR) - I have check with the original product documentation, the manufacturers web sites and they all claim that the card IS DirectX 8.1 compliant. I missed the bit where UBI said that it wasn't compliant - particularly on the product packaging - i will go an have a rummage for that article now so that I can fully understand your comments.
OTher than that - my comments about the software still hold true for ME - I have bought a lot of software from UBI and have always been delighted with my purchases. I found that UBI delivers goods as described on the box - well done UBI - it was for this reason I had no fear of prchasing Lock-On.
Like I have said previosly. Lock-On looks a fantastic simulator (I even got a new joy stick to play it!). I am (i think) justified in my sorrows until I get things back on stable setting - I will dumb down all the graphics settings to see if this makes a difference.
I appreciate all the (positive) critism and advice that everyone is offering - so please continue.
