X1600 + Oblivion = HDR + AA?

Hey guys, question here on the ATI X1600

Im ordering a ASUS W3J and my big question is, will Oblivion run on this computer with HDR and AA enabled like the X1900XTX can in a desktop?

I understand that the X1600 is a mobil version but does it still have this capability to run HDR and AA at once?

thanks guys!

 

The Mobility RADEON x1600 is much, much slower than the desktop RADEON x1900XTX - probably less than half as powerful. We're talking 8 single-shader pipes as opposed to 16 triple-shader pipes, fewer hardware vertex shaders, lower clock speeds, and half as much dedicated VRAM (256MB as opposed to the x1900XTX's 512MB). So chances are you can enable HDR if you keep the resolution down a bit, but AA is probably off limits - besides, higher resolutions looks better than lower ones with AA anyways.

 

It would be extremely difficult to handle both at the same time, agreed. You'll need at least an ATI Radeon X1800 for that. You could probably enable HDR up to about an XGA/WXGA resolution and be fine.

 

hrmm so oblivion at 1024x768 with HDR and 2x AA = a no go on the X1600?

 

Having HDR enabled at 1024x768 with other settings at medium gives me around 15-25 fps in Oblivion. Although our cards aren't identical, should be similar performance to what you should expect. With HDR off, I get a major fps boost.

 

Oblivion doesn't even allow you to turn on HDR and AA at the same time. If you turn on AA, it says you can't have both, then disables HDR if you enable AA.

 

It's a feature only for ATI X1000 cards.

 

Actually what kills it (btw its 12 pipelines) are the lack of rops (4, the same as the 9600 while the x1900 has 16) which put the whole scene together and apply things like AA and a 128bit mem bus. However it does mean you can throw as many shaders as you like against it.

 

So Chaz,

If you have an X1800 videocard with 256 MB you can play Oblivion with HDR and 2x AA on at 1440*900?

Thanks,

Charlie

 

I don't have an X1800, so it's hard to say . . if it was powerful enough, sure.

 

Might have to turn the resolution down to 1200x something but it would work.

 

And of course you can do it on Xbox 360, which has a GPU comparable to a X1900 with 512Mb. But that's off-topic.

Xbox360 runs Oblivion at 1280*768 with HDR and 2x AA I heard. And the videocard in the Xbox is a X800-based videocard with 256 MB.

The xbox 360 has dual x850's.

 

Bloom + AA owns HDR! and it runs smoother

 

The Xbox 360 has a highly modified, proprietary x800XT (or more correctly, a prototype x1800 - using a very early R500 core) with 512MB of dynamically allocated system/video memory. It also outputs not at 1280x768, but rather at 1280x720, aka 720p, a 16:9 resolution.

And yes, HDR and AA can be enabled at the same time only on ATi x1k series cards, and the SM3 compliant card in the Xbox 360.

 

Hmm, perhaps before it was possible. I have an X1600 in my laptop and it won't let me enable both. Here are the best sets I got quoted from a post on this forum somewhere when I did a search last week (specifically for a X1600 System, possibly a S96J):

"Video Quality Presets: Hit High
Resolution: 1280 x 768 (Widescreen)
Anti Aliasing: 2x
Mode: Fullscreen (V-Sync ON)
Screen Effects: Bloom ON
Distant Rendering: All three options to ON Texture Size: Large Tree, Actor, Item, and Object Fade: 100% Grass Distance: 0% View Distance: 100% Interior Shadows: 50% Exterior Shadows: 50% Self Shadows: OFF Shadows on Grass: OFF Tree Canopy Shadows: OFF Shadow Filtering: High Specular Dist: 100% Water Detail: High Water Reflections, Ripples, and Window Reflections: ON Blood Decals: High
HDR: ON"

I was going to follow that exactly except for Blood Decals Off (not for me) and 1024x res, I played it at that for the first week and got so used to the low res...and it lets me up the sets some more so why not - next time I play it I'll do it at 1680x1024 native .

But when I turn on HDR it turns off the 2x AA I had on. I have the latest patch installed, but not Shiver Isles expansion. Is this expected now with these cards?

Thanks,
Cat

 

It was possible before when I played, I guess a recent patch may have rendered that option obsolete because anything less than an X1800 would not be powerful enough to play it.

 

Did you also know the AA must be enabled in the graphics card options (Catalyst Control Center/ATT) rather than in-game to make it work with the in-game HDR option enabled with ATI X1XX cards?

 

Yes that is correct Ronkotus.

But like said before: I prefer Bloom with 16x AF and 2x AA much much more then HDR. The reason is that it runs much more smoothly. AF is a real must in Oblivion, it kills all that ugly blurryness.
