I am wondering why my OpenGL graphics look inferior to N4's (the system is
the same) and why they look inferior to the D3D option in NR2002? In N4,
OpenGL looked better (only with the system settings maxed out) AND had
substantially higher frame rates. NR2002 has the same higher frame rates
for OpenGL, but textures are blurred as you get close to them. I have a 64MB
video card, so there shouldn't be a problem??? Is there an adjustment in
some .ini file I should be paying attention to?

Thanks,

Marc

Well, for one thing, Open Gl is an unsupported feature.

If you look and the readme, there's mention of the sim having issues
with nVidia and Sound Blaster cards. I think it's the other way around:
those cards have an issue with the sim :)

There must be a way to adjust the mip level. I seem to remember that
with N3, some people had blurred dashboards and fixed the problem by
adjusting the mip level or something along that line. I have no clue if
you can change that in an .ini file or your video card options. Sorry I
can't be more helpful.

keep in mind what was said awhile back. With the larger textures used in
NR2002 it would take a 128 meg card to keep the game from mipping down.
Since D3D has a texture compression routine that OpenGL does not.

There is an adjustment in the player.ini under the graphics options for
texture quality. its a value of 1-100 with -1 being auto setting by the
game.

In N2002 D3D uses texture compression where as Open GL does not, some of the
tracks with a full field of AI will come in at over 80 megs of uncompressed
textures in N2002 (the max in N4 was about 40 as I recall). So your card is
dropping mips to make all of the texutures fit in memory.

Thanks for the info, I was just about to ask the same question, N2002
looks really crappy in OpenGL, even with all details on max.
I just wonder why Papy doesn't support OpenGL anymore? It worked
perfect in N4 :-/

What's funny is that the dash is crystal clear. It is the outside the
***pit textures that are blurred. I had the same problem initially in N4,
but cured it there with adjustments in the video card control panel.

So I guess we are stuck with crappier frame rates then in D3D or to go buy a
128 MB video card.

Marc, it is my understanding the texture compression or lack of does not
affect performance. It simply determines at what point a mip level is
dropped, so running in OpenGL you will probably drop a mip faster resulting
in perhaps a little more blurry of an image.
Personally, I like d3d better, even though I get alittle better framerate in
OpenGL. My framerates in d3d are still acceptible, and it looks better to
me.

If I set it to 100, it cures the problem largely. Some of the distant
scenery textures are still a bit blurred, but the full field of cars is
fine. So, it is a trade off between total clarity with D3D and 20-40%
better frame rates with OpenGL. By the way, I have a 64B video card. It is
obvious that if you had 128, the OpenGL would be totally clear and faster.
With 32 or less, you'll get a LOT more blurring, even when set to 100
(full).

Thanks for the tip!

Marc, the blurred OpenGL textures may come from the fact that 64tap (which I
think a value of 8 in the rend_ogl.ini will set) looks blurry on most
current graphics card. I suspect it'll look ok on a GF4. But for our older
cards, try setting that value to 4, which should select 32tap Aniso if I
interpret Papys approach correctly. That will not only look better (and
better than a value of 0, as suggested in another recent thread, too) but
will also increase the fps noticeably. If I'm right, that is...

If you REALLY want to keep the highest mips in OpenGL, edit the
rend_ogl.ini and change the TextureSetSize line to be 100MB or so
(remember the value is stored in bytes). Performance will likely tank
as as texture thrashing occurs, but it will look at good as D3D. This
will no longer be necessary once the OpenGL renderer is patched to
support compression.

Thanks Eric...I have all but the distant signs, etc. crisp by changing the
player.ini texture quality to 100. I can live with that until the patch
comes out. D3D looks great, too...it's just a fairly big hit in the frame
rate department. Of course you can't give a date, but is this patch
something that is already in progress and therefore we might not have to
wait too long (as in months plural) for it?

By the way, this is a shockingly good update to N4. Well worth the $'s for
me. I am thinking now about how difficult it will be to accomplish the same
leap forward for 2003!!!

Don't suppose there good be an updated OpenGL render for GPL in there too?

Hey I had to ask

MadDAWG

Once again drivers can make a world of diferance here. My OpenGL looked like
crud until I went to the 27.42 drivers. It looks as good as N4 now and has
comparable frame rates with Ansi-Filtering off.

It's kind of weird that the Sim has issues with the most popular sound card
and video cards on the market.
