    Heat Haze DX11 problem

    Hey, I need some help or someone with more knowledge about shaders.

    So I downloaded the port of heat haze and changed the application to DirectX 11.

    I applied the following settings:

Name:	heat haze prob.png 
Views:	27

ID:	31327

    It is set to the base layer in an 853x480 application. In DirectX9 I get a very subtile heat effect. If I switch to DirectX11 the effect is gone. The problem is not the effect itself, it works well but the problem are the texel values.

    If I change the settings from 0.0002 to 0.006 the effect works again but is so rough that I cannot use it. 0.005 disables the effect as well as any value lower.

    If you wanna try for yourself try to original example that comes with the ported shader. Set it to DX11 and change the texel values.

    Any idea would help as I really want to use DX11.

    Thanks!

    Sorry for double post but I cannot edit my post. I found that those limits are the only difference based on the selected runtime.

    DirectX9: 0.00011 is the minimum float value I can use
    DirectX11: 0.006 is the minimum float value I can use

    If anyone has any idea why, please enlighten me. Thank you

    Where did you got this port? Cause I don't have it in my collection, might be a incorrect port.

    Just ported it and it looks fine (?)
    Please link me the port you got, I want to check out what was wrong and who did it.

    Here's my port BTW.

    I see, I'm not entirely sure what's the issue there, seems pretty similar, but he definitely missed premultiplied alpha version.
    Mine seems to be alright, but let me know if the problem persists.

    Thank you NaitorStudios, after extensive testing I found that your version allows me now to switch to DirectX11 with my application which is great! Some of my older problems also vanished as I can use more recent shaders now!
