Well, is seems it was a driver problem…getting Catalyst 5.4 (6.14.10.6525) fixes it.
But, can anyone having problems with the shadows give them a try and tell me if it works.
Better to be safe than sorry.

I’ll just put out another call to ATI Graphics Card owners, to help me by testing my Engine.
Download the ‘SBML.zip’ in my first post, and the ‘Subliminal.exe’ update in one of my early posts (or later)…i’d really like to get it working on ATI.
Thanks

I just tried it with Catalyst 5.6, and still didn’t work.
I get a black window, with a white streak at the top.
Well, i’ve been testing it on an ATI 9800, and it works on 5.4…install that and try it (also, it has changed quite a bit since then).
But first, the ‘subliminal.exe’ is outdated…try just the straight zip file (SBML.zip), no updates. Try this before you play around with your drivers.

Ok, tried the straight zip, and that works OK.Guess the issue was with the subliminal.exe that I overwrote from the zip.
Looks good.

Excuse me, but what is a ‘7z’ compressed file and how do I decompress it?
Why don’t these people just use ‘zip’?
Yeah, the subliminal.exe was a patch to an older version of the engine (and the patch didnt work anyway), so im not surprised it caused trouble , glad to hear the new one works with the newer ATI drivers too, thanks.
Although, i have been working on some work arounds in case it doesnt work, primarily if the user has a crappy card then i made this: SBMLPGL.zip
It uses PseudoGL rather than OpenGL, (PseudoGL being a software renderer i made).

~10 frames on a GF6600GT, Athlon64 2800+ 640x480 with relief mapping.
I got a little bit more (maybe 20) without RM (LOD = 1) with a resolution of 800x600.
Indeed that seems VERY low to me, since the map geometry is surely not hight poly. You do frustum culling ? 
I’d like to know whether you’re using lightmaps for the soft shadows, cause it seems so, in the other case you are throwing in a lot of lights in order to approximate soft shadows, which would explain th low fps
You have tested the last .zip he posted here?
As he said its software renderer so its not a surprise its slow .
When I tested the normal version ( on 6600 GT ) everything was running quite smoothly
No, I tested the first one posted here… What you say is really interesting, but maybe the demo’s bottleneck is the CPU, and come on, an Athlon64 2800+ isn’t relly a fast one (maybe so much time is spent computing the physics, f.e.). In such a case optimzing them wouldn’t be a bad idea…
Another possibility is a different interpretation of “smooth”. As a Quaker, “smooth” means to me at least 60 - 70 fps However, I know “smooth” is understood to mean at least 20 - 30fps or so among mortals , which was definately NOT the case.
I downloaded the new version of this demo and now I see that its quite different from the previous one ( the previous one contained only some crates and a ragdoll and the speed diference between these versions is quite big. So you are right it is very slow now ( not smooth ).
Well, yeah is it slow atm, i have made some optimizations since then (Frustrum Culling, VBO’s and 2-sided stencil as extrusion is done in shaders), however they are not in that zip, i havent uploaded a new version yet, i plan to do so when i get a few more weapons done and a vehicle…i have yet to do any technique like PVS or Portal (if you know any good articles on PVS please tell me 
).
i have a GF 6600 GT, AMD64 3500, and it runs fine now (ranges from 50-120fps, 800*600 LOD=1), when i release the next beta it will be faster, not only because of the graphics optimizations, but the next version of Newton (the Physics engine i use) will have some good speed improvements.
I can get about 30-40 fps on the software rendered one (rendering AND physics on the CPU).
Anyway, Thanks for your input.

[EDIT] Also, the soft shadows are just cubemaps, nothing special about them, cept they are a cheap and good effect[/EDIT]

Why don’t these people just use ‘zip’?[/QUOTE]7z is 7zip. Why use it? It offers MUCH better compression, is open sourced, and is pretty nice.
The same argument was made when zip took over for .arc files, people were complaining why don’t they use arc instead of zip.
