Remember when the FarCry game got an "HDR" patch which added bloom? Only GeForce 6x00 could play it, but it looked damn cool in the shots.

Now, here are some shots with D3 bloom and since the engine uses real-time lighting and shadowing everywhere, the lights in the game were placed well, so *Bloom doesn't really overexpose it, and hell makes it look better!

ok, let's try it again:

Bloom is not HDR

There is much more to HDR than just glowing spots...

I love Doom 3, but those screens really show off the low poly bits of most of the game, plus it looks way overexposed. Still, could be a nice feature if used in moderation.

When in my topic post did I say Doom 3 had gotten HDR (through this method, as the engine does have HDR)?

I think it looks OK in 2 of those screenshots and then washed in the other 2. Bertruger especially looks like someone has a spotlight on his face in the first one of him.

Doom3 was meant to be the way it was IMO when it was released. Lightening it up is purely a matter of personal taste.

Most bloom methods produce an extremely washed out and blurry look, and unfortunatly these screens suffer from that as well. This is one of the reasons HDR (when set correctly) will produce a superior image quality compared to most normal bloom methods. Given the option of playing with or without bloom like shown in the opening screenshots, I think I'd rather stick with the non-bloom version, especially for a game like Doom 3 where almost everything is supposed to have a dark look to it. Though in those screenshots it doesn't really help that they were taken with the character self-shadowing which causes a few shadowing artifacts on the characters.

Oh, and shouldn't this be in the Doom 3 forum?

Maybe you didn't state it directly but you mentioned it more than once in your first post:

Maybe you meant something different than what you wrote but in any way it's always wrong to put "HDR" and "bloom" in the same sentence unless you are trying to say that both feature have nothing in common.

BTW, Doom3 indeed had experimental HDR support during the developping of the engine but Carmack completely removed any HDR support from the full version of Doom3, the only thing which remained are some non-functional HDR cvars like "r_hdr".

While we are at it, here are some interesting statements (http://www.extremetech.com/article2/0,1558,1745058,00.asp) by nvida's David Kirk on HDR which should make it clear why HDR is not just a bloom or general glow filter.

Yeah, and I'm pretty sure there is already a thread about this in there...

can't. disabled. it is talked about in detail in the thread in the Doom 3 forum.

Almost every pic of every game with this OGL bloom hack looks meh... tone it down like 75% and it will look tolerable.

Whoops! I meant bloom! First post fixed.

Anyway, the licencees get access to all the HDR and Shadowbuffer code that was ripped out of the shipping build. So a game based on the Doom 3 engine may very well be able to use HDR.

Also, what's funny is that when I switch to the EXP path, the game begins looking for HDR related stuff and a fragment program called "bloom.vfp" along with mid-point rendering stuff and also shadow buffer stuff!

Remember in the Qcon2004 speech, he said he had a version of the renderer that could switch from shadow-buffers to stencil shadows? He probably added HDR as well, and the EXP path is most likely that "renderer". However the required fragment programs for HDR and soft-shadows aren't there :-(

Could Carmack have just removed the actual fragment programs required and that HDR is actually in the shipping build of the engine (since fragment programs are "code") ?

Can you combine that with that ultra quality skin pack released a few days back?

Which Ultra quality skin pack? The one that I posted pics of?

Yes, I believe it can...

looks a bit overkill like he is glowing or something.. it does not fit in the doom3 game.

There were a few screens in the other thread, I recall one with an Imp, that looked fantastic, but yeah...these don't look all that good at all. :(

Its done with the HDRish Smartshader. Its included in the Catalyst Complete drivers If any ATI owner wants to give it a go. The shader is overdone and it blurs the picture, even in Doom 3.

I wouldn't call it an "HDRish" shader, just a general bloom shader would be more acurate.

I know, but thats the title given to it by NitroGL (the creator). Anyways, I've found a way to reduce the effect and it looks amazing in Riddick. Lights bloom without the overall picture being washed out. I'll reinstall Doom 3 and give it a go.

I recommend you drag each pic into a tab and use CTRL + page up and page down to switch between them and see the effect. You do have firefox dont you? ;)

I like 30% the best, even better than normal. If I do play through Doom 3 again it will be with this set to 25 or 30%.
