Widescreen Gaming Forum

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.
