software device displays images at good quality, directX and openGL do not... Whats the problem with image quality with directX and openGL why hasn't anyone fixed it...?

It would help if you provided some screenshots, because I've never seen a picture quality problem with Irr's OpenGL rendering when I use it.

Make sure your image file's dimensions are power of two. Only software mode renders non power of two images properly.

This is a problem and I have been waiting for the answer for some time now also, the one that said he has no problem. is lying or just an idiot, because it is there low quality blurred images in opengl and directx, but not in software device. im wondering what the hell the deal is when is it going to be fixed. my images are always powers of two but they are always blurred, what the hell...

You will need to show screenshots and tell us the size of your images.

Believe me there is no noticable image degradation if you follow a couple basic steps.

For example, if your image is 800 x 600, it will look rubbish in DX9 or OGL because it's not to the power of 2 (it will look fine in SOFTWARE mode though)

Supply more information for people to be able to help you.

Use this image sizes to avoid that problem:
1
2
4
8
16
32
64
128
256
512
1024

i found a way to solve this problem, the images must have one of these resolution:

16x8
32x16
64x32
128x64
256x128
512x256
1024x512
2048x1024
...

Kingpk, your second value doesn't HAVE to be half of the first....

I wonder how many people will post the exact same answer...

kingpk · Post by **kingpk** » Sun Jul 17, 2005 3:13 am

dances, i tried every of these resolution and every one worked. look at this:
you start with 2x1 and go multiplying per 2... so we have: 2x1 4x2 8x4 16x8 32x16 64x32 and so...

May I ask what video card you have? The reason I'm asking is that the software renderer is handled by the CPU and not by the video card.

Lol. You can use this too:
1x1
2x2
4x4
8x8
16x16
32x32
64x64
128x128
256x256
512x512
etc...

Works just as well...

LOL KingPK I SEE what the pattern is, I know they all worked. What I'm saying is that 64x64 works as well as 64x32, and so would 32x64, as long as the two numbers are powers of two they need no relation to each other.

Your problem might also be related with mip mapping. This have been discussed before, as well as power of 2s.
