Hey all,

It's been a while since I've posted anything, so I thought it was about time to set about a quick little program for all to play with.

It is basically a little 'world' which you can navigate and look at. It's quite pretty, and the rain, waterfall and grass swaying in the virtual wind is all quite relaxing I find.

Download here:

w,a,s,d - move
mouse - look

and some screenshots to provoke you into the download:

Just to note, I'm having a little trouble with the 'refraction' in the water shader, so its not included, and also, there's a wierd bug which causes the rocks to be hidden when their x,y,z location is out of the screen.

This was indeed pretty. I liked the grass and the terrain especially. Performance took a really bad hit though. I was averaging about 16 FPS Otherwise, nice work.

Support the indie!

Great work! I got an average of 32 FPS. Once again, Great Work and keep it up!

Nice demo, but I don't like the weather. Reminds me of the average weather in Germany. However, the trees are cool, I like the grass, the sound in nice and the rocks remind me of Halo (I also like Halo ). This waterfall-spectate-feature is quite funny.
Good work.

Oh yeah! I forgot to take the 'waterfall-spectate-feature' out, was just intended as a debugging feature for the particles..

oh well, as long as you liked it.

Any ideas as to why performance slowed so much? It's all pretty simple code. I haven't really picked through it in much detail though, but if anyone has any ideas?

It´s really pretty, but I agree that the fps is too low.
I got 33fps on my (8800 ultra, c2dE6750 with 2gb ram) computer and that´s the same speed as I get on the nvidia head demo.
yeah, they may have better software for development, but still

Apart from that, really pretty and very relaxing indeed. Good work!

I think its capped at 30, as it runs at 31-33 FPS on an Nvidia 8400GS too.

@hmm: Maybe you can release a version with no capping?

This is very cool. Atmospheric and kind of peaceful.

The water has some very messed up culling for me though. Not sure what criteria it uses. When i look at the base of the waterfall or behind it, i can see the water, if i look further downstream it disappears. This kind of stuff happens with shader stuff in my experience.

The rock culling was also a bit messed up. They disappear when they are partly off-screen.

Otherwise really cool. Love the rain effect. I tried something like that back in DBC, but the framerate was appalling. Are you using plains, cylinders or what? I'd quite like to nick that if possible.

Framerate was pretty low on this, but seemed fairly smooth. 23fps mostly, but if i looked at a whole bunch of trees, it went as low as 13. I have a fairly old computer though.

Also, it keeps fixing the mouse position. I went to another window and would have been completely stuck without alt-tab or ctrl-tab, and i don't think your average joe knows how to do this.

Looks good and about 30 fps.
Now just turn off the walking sound in water
when you aren't moving and have the rain come from
ahead of you when you move.

It's capped at 32 FPS. I use my better comp with 8800GTS, 2gib ram,AMD Athlon 64 x2 dual and core processor 5000+.

One thing, maybe increasing the speed of the rain, it's nearly slow-mo man.. Compared to real rain.

the trees could use some animation to match the grass, but excellent job on the leafyness

The capping at 30fps is a bit wierd. I get it too, and im sure its at sync rate 0.

And does anyone know how to get rid of the strange culling problem with the rocks. They disappear when only partially off screen...?

Been back to uni this last week so i haven't been working on it much. Will hopefully get some good tree motion in, and possibly a little bit of lightning to go with the thunder.

edit: sync rate 60, plus the extra syncing involved in updating the water shader may halve the fps...?

Can set it to sync rate 0 and remove the 'cap', but will be a bit unstable. I haven't bothered to code in any delta time system. lazy

Why do you need another sync?


By putting a signpost in the middle of nowhere, you're making it somewhere.

The water shader uses multiple cameras do grab different images to apply to the water. The function that came with the shader has;

sync mask 0x80000000
fastsync

Thought this might be causing the slowing maybe. Not sure. Haven't really looked into it yet.

Just checked. And removing the water update function speeds the program way up to the 60 fps max i've set. Does anyone know much about using the shader to get fast results? Its the one in the Free Shaders Pack.

You need to multiply the sync rate * the number of cameras for this to work. trust me. Try it and see.

how ya culling them? LIT port? If So.. search for the 0.5 value that is multipled when calcing the sizes, and make it a ONE.

(Makes cube and sphere only work on half the objects size!)

Yup, I had this problem use "set object radius Object,-1".
Also, It only ran at around 15 FPS on my computer but you might be able to speed it up by cutting the number of raindrop objects in half and doubling there speed, Idk if it would work but I would try it.

Neato!

I know why the fps is slow. For some reaon windowed projects run a lot slower in DBP. Make it full screen and you'll see the difference in FPS.

I've had windowed projects run at over 4,000 fps before.

Wow, I'm impressed. What really made it realistic was the water, which is easily the one thing to ruin realism. Looks a lot like Halo too, but with more vegetation. I wish it ran fast on my Radeon 9550, but who am I kidding? I got about 16 fps, except when looking at that cool waterfall, where it went to 9 fps. Superb work.

Not sure why mine went slower, could be a number of other variables on my computer. Ah well, amazing demo just the same.

Depends on the comp and what you were running. Probably would run even faster full screen.

What i dont understand, is why other directx9 engines can handle a scene like this, asif it were a 6 sided cube, yet the dbpro engine has a strugle handeling a tree?

Btw i get 33fps

Because DBPro is basic language and Basic languages are usually slow but DBPro is actually pretty fast as basic language..

If you want speed use C#/C++ or for more speed Assembly

Sadly.... in today's Microsoft world - you don't gain so much jumping to Assembly - I mean your code will run lighting fast but you're still calling whatever API's usually written in C++.

Frankly - (I'm an assembly fan BTW) - if you really are after premium frame rates you need to jump directly to DirectX - DarkGDK is MUCH faster than DBPro - but Directly Accessing DirectX is another BIG jump in frame rates!

Switching to Assembly is great - but if you're writing fairly tight code - and calling API's like Direct X anyways - then... going through the trouble of assembly might be a bit much.

However - for involved physics and AI - I think assembly might do wonders for you.... but this demo isn't about AI or physics - as much as Pretty.... and it is pretty.
