I remember JLV saying that when there are alot of billboards taking up the whole screen, it uses alot of fill-rate or something like that

[yzmxer608]

Billboards for the particles? I know the game lags if you use too much of your graphic memory, but mxs can't be that reliant on texture usage compared to giant maps and environments in the CoD series or Bioshock for example?

Yesterday I played some hours at online because it was load of nice and fast guys plus good tracks and me and Jay tried talk on Xfire and I though if would be possible JLV make something to MX Simulator can be read at Xfire ? I mean for count how many hours you've playe dthis week and stuff.

I think it is more about getting Xfire to support MXsim, than the other way around. I remember that puma or someone did a request on the xfire forums about that.

The particles are billboards. The fill rate killer is when a bunch of roost is right on the camera. You can easily have more than 20 roost billboards filling the whole screen in that case (each wheel can throw 1280 particles per second). If you have 20x overdraw on a 1280x1024 screen that will require 1,572,864,000 pixels/second to maintain a 60 Hz frame rate. I'll probably put in an option to not draw roost billboards that fill the whole screen. Just hiding the particles that are within 3 feet of the camera would probably fix most of the problem.

Wow that's a lot . I normally use the first person camera, so it only affects me when I'm riding behind someone. Was just wondering how/why they worked .

What do you mean by overdraw though?

[DJ99X]

When they take up too much of the screen / the whole screen and then some. I think

Hey JLV, yes or no answer. Will this friction thingy be done in 12 days?

[yzmxer608]

Oh, just drawing the ones on the screen a smidge past I think is a good idea then. If that's what you meant by 3 feet within the camera.

Overdraw is when the same pixels are drawn more than once. Offscreen pixels are clipped away so they don't affect fill rate at all. Say you cover the whole screen with a rectangle. You now have no overdraw since each pixel has been drawn exactly once. Now draw another rectangle that covers the whole screen (in real apps this will usually be something with an alpha channel, but not always). You now have 2x overdraw, since every pixel has been drawn twice. The more overdraw, the more fill rate you need to maintain the same FPS.

Sorry, I don't give yes or no answers. The friction thing will be done on 9/2/2009 at 10:15 PM eastern time. (Actually, it's already done but I want to add a couple more things.)

[DJ99X]

Hooray

How did it turn out? Noticeably different?

[yzmxer608]

Thanks for the explanation for the overdraw, made it very easy to understand.

Looking forward for Wednesday now .

So, given that JLV is in a question answering mood, are you by any chance going to participate in the track contest? That would be hilarious if you won your own money.

[DJ99X]

I was also wondering if he was entering. Be cool if he did

[jlv]

I don't think it would be fair to do that. I'm going to make a new track to show how the new traction system works though.

Hooray

You can definitely give the ground a softer feel with the right parameters. Mud really feels like mud now. You can make it very slippery initially while still holding you up instead of just slipping away like you're on ice. For regular dirt it's less noticeable, mostly because Coulomb friction closer to being correct in that case.
