ok just wondering.. I can't seem to find the answer via google

Prior to this EyeFinity thing being announced. my highest playable resolution is 4320x900 via Th2G.

my rig runs Win XP Pro 32 bit. and all the games I play is either on DX8 or DX9.

I got 3x 24" monitor at 1920x1200 native resolution. so triplehead will be 5760x1200. is DX8 or DX9 even capable of that resolution in their specs?

I think the specs resolution for DX8 is 4096x4096


I would LOVE to play my older titles at 5760x1200 but not sure if they will run at that high resolution even if I have the hardware.

Not sure that DX8 titles will do higher than 4096. I suppose they might if on the correct OS (Win 7)... not sure. I imagine it depends how DX8 calls are made in DX11, and whether they've updated .dll's etc.

depending on the games, if they are capable of playing at high resolutions then yes if not then they wont work at the high resolutions, it would be great to see if a game doesn't support the high resolutions that the screens readjust and only use one screen to display the game. Unless there is a fix to make the games work on big resolutions which fixes exist on this site for certain games. the cards run almost like th2g but bigger with less restriction. good luck

As far as i could search, there is only a GPU limit, not a directx limit. In an old topic we saw that you could pass the 4096x4096 limit what we thought it was directx 8. If i remember correct then the GPU had a texture resolution limit of 8192x8192. If I remember correctly the first card with that gpu texture resolution limit of 8192x8192 was the G80 (Geforce 8800 series)

When I asked about maximum resolution I was told that crossing the 8000 pixel boundary starts to cause hardware issues, but with single-GPU Eyefinity displays easily able to render @ 7680x3200 it doesn't seem like much of a problem for the near future.

There are a few threads over on the Orbiter space simulator forums related to pre-directx 9 resolution limitations. I've experienced it first hand with Orbiter. orbiter won't even do 3840x1024 on the version that is pre-directx 9. I think the maximum limitation was something like 2048 pixels wide.

DX enumerates the displays that the display drivers are telling the OS the display and graphics board supports. Once a Display Group in configured in CCC the driver reports to the OS the available Display Group resolutions and then DX can pick that up.

You might have some success with older DX9 games. I have run BFMEII @ 7680x4800.

Are the 5000-series cards 8192x8192 theoretical maximum?

at least golem.de said so (8000x8000 max i think) in their article about eyefinity.

I hope DX11 has upped that limit, and that the 5x00 cards can do higher... at the minute, sure, (3x2)x2560x1600 is less than 8192 pixels, but what would happen with any higher res screens? Because they will come.

Sounds like EyeFinity does the same as TH2Go there - reports to the driver that the screen is 'x' by 'y' res, which is then reported to DirectX. No indication of what the DX limit is.

I'm hoping we can break the 8,000 or 8k pixel range. Without that you can't do 1680 or 1920 in a 5x1 landscape.

And I was told at the launch event: "Going over the 8k pixel barrier starts to cause hardware problems". I didn't get any more details than that.

I just did a little test with BFMEII. The game starts and runs @ 8192x5120. Starting the game @ 8320x5200 does let the game run, but it automatically resizes down to 640x480. Appears as though something tells the game "That resolution won't work", so the engine defaults to the lowest standard resolution. I only run DX9, though, so I don't know how DX10 or 11 will fair.

Might be a hardware limitation, too. What's the pixel limit on G80 cards?

4th post in this thread:
1) 7-series and below cards were 4096 max pixel width. 8-series and newer are 8192 max pixel width. It is a hardware limitation, not a DirectX version limitation. 8192 pixel width works in both DirectX 9 and 10. I've ran a setup in-game with 6400x1024 awhile back to confirm DirectX 9 works just fine past the 4096 supposed limit if using proper hardware.

Not sure what his source is. You remember where you got that info, Brad?

From practical experience and a tool in the directx sdk that shows hardware capability. The person that clued me in on this was the author of SoftTH. The original thread about breaking past 4096 was in the SoftTH forums somewhere. In particular I also questioned it before I did the 5 display softth+th2g test and he linked to a download of the utility. I sense then broke past the resolution I used in the 5 screen test with 4 24" running 7680x1200 using 2 DH2G and XP Horizontal-Span mode.

DX Caps Viewer also should show the hardware max limits if ran on a 5000-series card. That would be one good way to know the max specs.

I just found the original post over at SoftTH forum:

could you supply a link to reference that 8XXX series can in fact do 8192x8192?


You can check it yourself with the DirectX Caps Viewer: http://junk.kegetys.net/DXCapsViewer.zip (From DirectX SDK)

Go to DirectX Graphics Adapters/Your card/D3D Device Types/HAL and select the 'Caps' key. On the right it will say the 'MaxTextureWidth' and 'MaxTextureHeight' values, which should be 8192 for at least the 8800 series cards.

That is for SoftTH use, I'm not sure about limits with TH2Go and others.


http://www.kegetys.net/forum

On a separate note, this brings up a new set of options past the 6 EyeFinity display limit. You can most likely now use multiple DH2G or multiple TH2G + EyeFinity to push some serious sized display grids. (as long as you keep under that 8192x8192). 7680x3600 using a pretty crazy EyeFinity+6 DH2G Digital. If you have no budget restrictions how about EyeFinity+6 TH2G Digital in portrait mode pushing 6300x5040? There are some pretty shocking sized single card video wall options now if you chose to mix solutions together. When even humoring insane things like that it would make more sense just to use 1080p projectors instead to achieve screen size. :shock:

Excellent. Thanks for the info, Brad. As it just so happens I have the DX-SDK installed and I didn't think to check it at all. :D

Can't tell by your sig, but are you running DX10 on Vista? If so, I think we have confirmation that 8192x8192 is the res limit. My MaxTex numbers are identical for my 8800GTS. Have you seen anything that indicates DX11 might have increased these limits?

Also, it hadn't even occurred to me to think of a combined EF + TH2Go system. I'm going to have to daydream about that now for a little while... ;)

3x2x2560x1600 is less than 8192 pixels, but not 6x1x2560x1600 in horizontal span. Even a more realistic setup for people already has 3x24 would be 5x1x1920x1200 --> 9600x1200 would not be bellow 8000 dx9 max limit.

It´s seems we will be limited for some time to 8k max resolution

with all these talk of DX limits

what about OpenGL?

are the any new games comming out that uses OpenGL?
