Is OpenGL same as Glide?
Tried the OpenGL driver for the first time in GPL instead of Dx7 driver. It
worked fine until I left the track. The interface screen was completely
black. Still had the cursur but took me ages to escape GPL!

Any ideas anyone?

OpenGL is not the same as Glide.
GPL supports Glide and Rendition based graphics cards as it is shipped from
Sierra. OpenGL and later D3D support was later added by two unofficial
patches (actually there were two D3D patches for a total of 3 patches).
Using a GF3, the best option for GPL is the newest D3D driver available from
http://www.papy.com . The OpenGL patch has been found to be rather buggy by
many people IIRC.

Thanks Ian,
One other thought I've had, and I know that I'm gonna be laughed at for
this, but I am a non-entity when it comes to understand 3D technology but
would it be a massive job for GPL to be upgraded to Dx8? My concern is..how
long will it be before later versions of DirectX will lose downward
compatability? As I presume it's Microsoft owned and we all know that MS
OSs' have a 'shelf-life'. Can u imagine life without GPL? Remember that so
many old games are now unplayable!

I mean, our modern computer will eventually be tomorrows dustbined

Now I can't claim to be a serious 3D guru either but I think you are kinda
missing the point here....the DX version will not affect performance
significantly - as I understand it what matters for 3d performance is the
Rasteriser - i.e. the 3d graphics engine you are using.

With a Geforce 3 you should definitly be on the D3D version & not OpenGL. I
used the OpenGL version succesfully for quite a while when I had a TNT card
but since upgrading to a GeForce 2 GTS I've changed to D3D & its better
(hard to say why, it just is!).

As otherwise posted, Glide is for Voodo cards & Rendition is for, well
Rendition cards!

I stalled (and stalled!) until switching from DX-7 to DX8a (just 2
weeks ago, when F1-2001 required it to run). I still have compressed
Win98 backups with DX7 just.

The first program I tested with DX-8 was GPL. It worked fine, no
trouble at all (using d3d patch and Geforce video).

DX8 was designed to be "un-installable". But there are software
programs (3rd party) designed to remove it anyway :)

I don't know about Win95, but if you're running W98/W98se, it should
be fine.

I wouldn't worry to much about older games and newer versions of DX. One of
my favorites is DTR which is actually DX5 code but still runs fine with dx8.
When you buy a new game it comes with the current version of DX even if the
game dosn't require it. So far I have not found anything that won't run on
DX7.1. Even games that say they need dx8 like N4.

F1 2001, at least for me. I told it NOT to load DX8 on the first install,
because I didn't trust it based on my N4 experience. The program wouldn't
work. I re-installed, and let it load DX8, and it works fine.

Hi,

has the problem of misplaced menu graphics after returning to the menu from
a race been solved by now. Couldn't find anything on papy's website or
simracingmag.
