HDR+AA in Oblivion. Smooth light at end of the tunnel?

Toggle sidebar Toggle sidebar
Well, I must say at first that I'm not surprised. It was pretty clear that there wasn't much of a technical limitation to using AA at the same time as HDR in Oblivion; it seemed pretty clear in the Beyond3D interview, (second page) when they merely mentioned that "Blending in the pixel shader would end up being prohibitively expensive given the complexity of our scenes," Rather than "Blending in the pixel shader would be completely impossible given the pixel shaders used for HDR."

The only real shame for most of us is that we don't have Radeon X1k cards, and use our old "X"-series cards. (like my X800XT and your Mobility X700)
 
Glad you saw this posted in the other thread too.

Yeah it'd be nice to have it add some other features (like maybe integer H/DR) for those of us on slightly older gear, but I may drop by a friend's place and see how his X1600Pro handles the two together. I would n't be surprised if for him is is 'prohibitively expensive', but still nice to have the option none the less.
Now if they'd only get on with the Mobile X1700 and Meroms. 8)

I have to say though I am surprised it was 'official' ATi who did it and not a tweak by one of their developer guys like Humus, but I guess it's really Chuck's patch made 'official'.

It would've been nice having it before a bunch of the reviews were made (many will remain unchanged forever), but perhaps Brandon at FS will consider this patch when re-benching (already made him doo so much! :twisted: )
 
Is there anything specific you ened to do after installing the driver? I thought the options page was coded such that you can't enable both, even if the hardware permits it...

I'm not sure since unfortunately like NotTheKing mentions, ain't got the hardware to do it.

But I'm sure Cleeve will be more than happy to peruse the readme file and report back his findings. :mrgreen:
 
You assume there's a readme. All of this is unsupported, and all my efforts to find an answer are turning up nothing. Still working on it. If I find an answer will post.. but if somenoe knows, it'll save me hours of searching and trialanderror.

True I did assume that because usually there is.

Obviously it's supported by ATi since they're hosting the HotFix. As for turning up something, 2 seconds in the forum gave me the following...

So accoring to this;http://www.elderscrolls.com/forums/index.php?showtopic=348482&st=20#

Enable HDR in the game and let the CCC ovveride the AA settings.

Usually ATi recommends AGAINST doing this for AA and AF, like they did with F.E.A.R. because it usually causes problems not fixes them.

Oh.. so i've been running with AA and HDR since I installed the update? (I have force set already). Damn. Well, if it makes you feel any better, it doesn't do much. If you're running at 1280x1024 or higher with HDR enabled, you really wont notice... and that's with all the settings maxed.. and yes, i'm running a capable system. 😛 1900xt, 4000+, bucket-o-RAm, etc.

Just finished Oblivion though.. all the main quest lines.. defeinitely worth every penny.

oh, and it's not technically supported by ATI. They're hosting it, but they've got disclaimers posted all over the place saying it's not their problem... 😛 Not to be a nitpick. I hate it when people are nitpicks on a forum. 😛
 
It's kind of of topic, but there's actually a funny story attached to the release of the driver. It seems ATI's press announcement was filtered by HEXUS's spam filter due to it's "dirty" innuendos. For interest, there's also a brief bit of speculation about how HDR+AA is implemented.

Geek bit: I'm fairly sure it's nothing much more than a change of backbuffer surface format so that MSAA resolve works and then scanout from that as normal. So the driver just allocates the 'right' surface format at runtime when the app requests the non MSAA-able format, and uses that for rendering.

Well it totally doesnt work for me on my X1900XT!!

Have installed it 3 times, running on Cat6.3, followed instructions (like thats difficult) and as soon as I enable HDR its jaggy city all round.

Anyone had similar problem and fixed it??
 
Thanks but doesnt work in the slightest. In fact even with HDR off and AA turned off in Oblivion it will not accept my force AA option from CCC.

Anybody else got any idea's, this is really pi@@ing me off as I want HDR but I am not playing a game like this with jaggies on the screen, makes it a bit of a joke.
 
I'm awaiting my X1900XTX in the mail right now, but in the meanwhile I wanted to download the drivers. Do I need Cat 6.3 AND the "chuck patch" or is the chuck patch an all-in-one setup?
 
It does work... ignore the people claiming otherwise.

Download and install the Cat 6.3. Then install the Chuck patch over it. When it asks about overwriting the older files, say yes.

To make it work, enable HDR in Oblivion, and force AA in the Catalyst Control Panel. I also heard you need to leave Catalyst AI enabled... although Standard settings are fine.

Enjoy. I'm only running an XT, not the XTX, and it's beautiful, even with my single-core 4000+.
 
Malph: It sounds like you've got a corrupt driver install. Disable your card in Device manager, reinstall the latest drivers, install the chuck patch, reboot, enable the card again, and it'll detect. Then play with your settings. Make sure Catalyst Ai is on, or else it won't work.. at least, that's what i read. I personally didn't have that problem...
 
no worries people ATI have released their april drivers which include a fix for HDR+AA.

It does? Tom's News says that 6.4 does not include the "Chuck" patch.


Also, just for the record, you can just install the Chuck patch and everything will work fine. I installed it as my drivers (never installed Cat 6.3) after reformating and everything works great (not that my x1600 pro does HDR with AA very well, but I wanted to see if it would work...)
 
I guess no patches are needed for Nvidia boards?

As I understand it, Nvidia's cards have hardware limitations that prevent it from doing both. So, no, no patch needed because they can't do it at all.

It really annoys me when people just jump onto a forum and make stupid statements like this. Obviously it works for some people, but not for others. I am on several other forums where other users are also having no joy with the patch, I would guess about 20 people. I have seen about 50 people say it does work, so it is not universal and is clearly affected by some variables on peoples PC's. The fact that it works on your PC does not mean that you can make a sweeping statement that other readers should ignore the comments of people who say they are having a problem.

Next time you want to be "helpful" you should qualify your statement properly.

Ok, just cleaned out CAT6.3, also used catuninstaller to make sure, put CAT6.4 in, and no difference at all. According to the readme they have fixed the crossfire issue, they make no mention of the HDR+AA issue.

Going to try chuck patch again on 6.4!
 
Cool. It does't work on that either.

Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr!

This is ridiculous.

I have tried every way to set it and it won't work. Turned HDR off in Oblivion, and turned AA off in CCC. Then went into Oblivion and switched on HDR. Then left Oblivion and switched on AA (4x), went back into Oblivion and no AA. Tried with and without AI.

ah heck.

Looks like I wil have to wait for CAT6.5!!
