What would cause this?

[Tweek]

I'm experiencing jaggies on the textures of Rick's Hawk, but I've yet to find a way of solving them. There's nothing wrong with the textures or the aircraft itself, I'm sure of that, but it's just something on my system that's causing it. I would have thought resolution, texture size and anti-aliasing settings would come into play here.

I'm currently running at 1280x960 and 24x anti-aliasing with multisampling. These particular textures were reduced from 2048 to 1024, but that didn't seem to allieviate the problem. The screenshot has also been cropped, so this is an 800 pixel section of the screen.



I felt like this is more of a widespread issue, which could (and sometimes does) affect more than one aircraft, so I've posted it as more of a general query, rather than an issue with the Hawk.

Hi Mate,

I'm not seeing jaggies in that shot. :think:

Really don't think theres any need for 24 x AA though. 8 is usually more than good enough. Can you explain what bits you don't think are right in that shot?

That's quite bizarre really! I can see them along the white edges of the pattern, and on the pitot probe. I can most definitely see them in the simulator, aswell.

We had this the other day where I and one or two others could see jaggies on photos, and some couldn't! Very strange.

Saying that, what resolution are you running your desktop at? I suppose that could affect the appearance of any jaggies in screenshots. I'm limited by my monitor I'm afraid, so I can't test that out myself.

Hi Ben..

I can 'sort of' see jaggies on the very thin white pin of the red fuse line but I don't think you're gonna get away from that as the lines are so thin. Anyone who's ever flown a model painted up in BEA Pin will know exactly what I mean. Get it at the right angle (and there aren't many) and you get away with it. Outside this 'right' angle.. it all goes super jaggie :roll:

Ah right mate! I get you now. Its not jaggies as such. You will alwas get that type of effect when you have high contrast colours bordering each other.

I always think of Jjaggies being the edges of the model, when you have AA off or something, hence why I couldn't see wht you were meaning. Sorry matey.

I just loaded the beta up in this paint and I see exactly the same at the default zoom. Zoom in to 1.50 or higher/closer and it goes (at 2.0 it's gone). As ben says.. high contrast colours will cause this. Having hated doing the DHL paints for the Vanguard (and these have quite thick lines).. I can only stand to look at it from close in. If viewed from default or further back, it goes to crud (these are white/burgundy) ;-)

Never heard of AA going as high as x24 before. Just shows how far behind I am!

Indeed, the jaggies do go away when you zoom in, but then you lose a lot of the lovely scenery that you also like to look at, so it's probably not the greatest of compromises.

As for 24x AA, it's 8x with 'Edge-detect' on, which I can only assume enhances it 3x. There's Box (8x), Narrow-tent (12x), Wide-tent (16x) and Edge-detect (24x). Don't ask me what they mean because I haven't got a clue.

Any higher tha 4XAA and I'm in trouble

Looking at the tail lettering and other thins it looks like you have too much sharpness or similar

The image in not clean

Narrow tent.. wide tent.. edge detect.. :o Oo-er Tweek.. I don't see that on any of my settings on this pc (GF6800GT using NVTray). Wonder if it's there on my ATI system :think: Anyway.. I forego most of the posh stuff on the Nvidia pc just so I'm able to see the spinning aircraft. I know you can get around this by going windowed but even that is too much trouble

That looks exactly like the jaggies I've always seen when textures don't have mip maps included.
I've often felt like the only person in the world who sees it, but perhaps you do too!
I used to think it was a peculiartity of ATI video cards, but I currently have Nvidia and it's just the same.

Not sure about the Hawk texture format as it's a proper FSX model, but if you really don't like jaggies, it could be worth a try to add mip maps to the textures and see if that helps.
Make sure you back them up first though!
