3D Vehicle Dynamics Engine Demo (New Version)

[pifreak]

42 average FPS
35-50% CPU usage

with:

windows xp pro
pentium 4 2.4GHz CPU
1024 mb pc-3200 memory
256mb PCI NVIDIA Geforce FX 5500



bad things:

driving fast diagonally

the squares hurt my eyes and almost give me a seizure...okay maybe not but it is still a headache XD

[SunshineKiller]

awesome, 60fps avg.

[gholdys]

I invite you all to take a look at the newest version of the demo! It contains more objects, cel shaded graphics and an improved physical model. Any comments are welcome :-)

Cheers,
Grzegorz

No good here (although previous version worked fine). No textures, <1fps, no key response...

I have no shaders on my graphics card

Hmm. Maybe I should create a version without GLSL shaders 

[h3ckboy]

when I back up to a wall and it blocks my screen and the walls ort of fades. colourful lines fly aorung my screen.

21 FPS if I dont move. and it steadily goes higher tah longer I move. highest I got was like 35. excpet when I turn then it goes back down to 21.

Somehow it didn't work for me with Sun Web Start launcher (6u10), only briefly displayed the window and then quit (probably crashed). With OpenJDK, it works - and quite nicely at that. I'm running Ubuntu Linux here. The physics feel solid, and cellshading + stencil shadows look nice. Keep up the good work!

I guess I could try Sun JWS with Java console open to see if anything turns up..

I have uploaded a new version, that automatically disables GLSL shaders if they are not supported.

This is quite odd. I use Sun Java (6u11) under Fedora 10 and it works just fine. If you could run the demo with a console open, that would be great.

The FPS will at least partially depends on the complexity of graphics that is being drawn. Some models are simple (i.e. the fence) and render quickly, some are more complex (warehouse with cones in front of it) and require more time to render.

The issue with colourful lines is new to me. I will have to look it up. It's something with blending, most likely.

Thanks for the feedback h3ckboy :-)

Hah, this is typical.. I enabled the console, started the game and boom: it worked normally. Nothing was printed to the console. Don't know what that problem was before, I tried twice and it just quit before showing anything apart from a white window.

Very cool.

This is important! Thanks irreversible_kev. I'll fix it ASAP.

[gouessej]

It works here now, thanks  14 FPS, Mandriva Linux 2007, Sun JDK 1.6 update 11, ATI Radeon 9250 Pro with an open source driver.

[SimonH]

Still no good here - (this is a dog of a machine though, so don't worry too much!)

[gouessej]

A french guy that has an Intel GMA graphics card said it is extremely slow: between 0 and 5 FPS. I don't know why.

I have an Intel graphics card on my laptop and it works at <20FPS. Nevertheless, there are probably a few things, that could be optimized in this demo. I'll look into this.
