Low frame rates and a tad laggy, but it worked. I am very confused by the configure, if only for the fact that I don't know what any of that stuff means ;_;

Erm, yeah some settings just wouldn't load. I don't know if they were in the process of doing so or what. Namely my native, 1280x1024 never loaded :-?

EDIT: Also, I couldn't help but replace your horrid texture for the ground with one of my own.


His name is Steve. He's a Blalagaphlakasaurus, and he compresses quite well. If you want the texture file, go ahead and say so. Believe it or not, it actually looks quite well in game.

EDIT2: God damnit. I also forgot to mention that running off the edge puts me in an infinite "omg I am totally stuck here" space. Kinda like I'm standing in a box made of air. Perhaps the character is a mime? LOL.

Pritch, you really don't have to know what they mean. Everything is set from lowest quality to highest quality. So, if you go with lower setting, you'll have better performance.

Also, I was wondering if any of you tried to change the value in the gen.egs file in the data folder? I used 100 by default, which really is a bit high. You might try setting it to something <=10. I'm adding a culling routine so that it wont draw shadows for non-terrain objects that are too far away. Until then, setting the value in that file lower should help.

I do get much better frames with very few objects but it really seems like the shadows really shouldn't eat as many frames as they do. maybe with that culling thing it'll help out a lot.

0 objects = 200+ fps

100 objects=20 fps

That's not bad really. It's somewhere around 175,000 polygons per fame, using 100 objects. ;)

I'm not sure if the new drivers helped, or your optimizations. I should check Sokoban 3D.

640*480 - Any combination gives 1-2 FPS, even when using the least demanding setting.

320*240 - I get 7 FPS. I tried all parameters and always get 7 FPS, unless I turn on the shadows (then 1 FPS). If I set the number in gen.egs to 10 I get whooping 34-41 FPS, which is great. Even if I put anti-aliasing 16x and texture filtering to LINE_MIP_LINE. Again, if turning shadows I get 1-2 FPS.

Anyway, I don't understand why 640*480 kills FPS so much.

I'm getting the same peformance as Lachie. Very slow and jerky no matter what settings. Plus I am getting that "Z" error thing at the bottom.

Guys, zFail is a a method of producing shadow volumes. That's not an error. ;)

Interesting, but...

Interesting engine.

On this 450MHz P3 with 320MB RAM and 4MB onboard video (S3 Trio3D), I get just over 1fps, with it at 320x480, color depth 8bpp, no antialiasing, no anisotropic filtering, shadows off, texture filtering at LINE_MIP_NEAR, the app windowed, and vertical sync off.

My "normal" box (2.66GHz P4 w/512MB, 256MB VRAM) is temporarily decomissioned until I can either get Linux, ReactOS or a legal XP key for it, so I'll post back if this thread is still active when that box is working again :D


EDIT: Putting a "1" in gen.eds and setting Texture Filtering to NEAR -> MIPMAP OFF gives a small performance boost, and I'm actually able to use the game. It's probably running at 15fps or 18fps now, which is actually pretty good :D

I really think you should add a "toggle FPS" key to this thing by the way!
