You said the same stuff when dx 10 showed up – nothing special – and then again  – dx 11 nothing special. We'll see dx 12 in the future- and you will say it again. Most of the people use XP….this is why we will stick to dx 9. And one more thing is that you can run dx 10 on windows xp and you can run dx 11 on Vista and you can run dx9, dx10, dx 11 on windows 7. I could ask another question – what would you do if Windows 8 would drop support for dx9 – as a marketing decison.

We simply look at the product and Lumion works fine with DX9. As a user for Lumion I would only see drawbacks in a DX11 version because it would mean you can't run it in XP anymore. What does DX11 have to offer to the user experience? Very little. Like I said, just look at what's currently available using DX11.

What we would do if windows 8 drops DX9? Simple: there won't be a Windows 8 version until enough people use Windows 8. It's the same deal with Apple. It would be awesome to have a Mac version but there are simply too few people who depend on a Mac. A company like Adobe can afford to create a version for every OS version but we can't (for now at least). It's a numbers game. There are three options: I) DX11 version b) Multi DX c)DX9 version. We pick c) because a) and b) generate less extra income than it would cost us to implement those solutions. So essentially we will make a loss on those options.

To be honest there are just a few people requesting DX11 and I'm sure there are even less who have good technical arguments why they absolutely need DX11. On the other side I can guarantee a mob will be in front of the office with pitchforks and torches when we cancel Windows XP support. It's a matter of time. We dropped support for Windows 98 when the time was right and it will be the same with Windows XP. Now if only Microsoft added WinXP support in DX10.... I hope this never happens again.

Im just trying software now and must say i am impressed - finally a modelling program that can output quick renders in a few minutes...

But i was also disappointed that for a GPU based software no crossfire support.


 Regardless of the DX verison, there must be a way to utilise crossfire / SLI … i can play older games through DX9 and get full utilisation

and obvious performance benefit   ( usually 60% to 80% gains in DX9 )


My system is  i7 860 , 2 x HD 5850 in crossfire, 8GB memory but im finding the complexity of the model i am using is still dropping frame rate to 10-15fps , and the extra graphcial horespower i have sitting idle would come in handy . 


 I have confirmed with  MSI Afterburner.. one GPU sits in idle the whole time i use the software which is a shame.

 So, if we can improve the SLI performance and have 64 bit what's the benefit of DX11? End users wil barely notice. Just pick up some games to try and find the differences between DX11 mode and DX9 mode. The differences are marginal.

useless DirectX 11 code…


You can enable DX9 and D11 functions inside Lumion like all games do. Software and games are complex, I know. 3DS Max works on XP as well as on Vista and Windows 7, on Vista and Win 7 you can enable DX10 shaders.

Why don't you implement this feature?

Also I notice the software runs in windowed mode ..


this- to my knowledge – running in windowed mode is not supported by crossfire or SLI. … need a full screen mode  [ not fullscreen window ]  …. 


so i would be suprised if anyone noticed marginal benefits in crossfirex or SLI as this is simply not supported by the hardware …  i have tried forcing crossfire with secondary app ( ATI crossfire xtension )  but as it runs in a – fullscreen –  window it simply doesnt work ..


It would be great if full screen option was availbale so people with multiple GPUs could maximise the benefits of the software. 


good link explaining how to get SLI / Crossfire working if not supported by Nvidia / ATI current driver set ... not Direct X related issue.

Yeah, currently Lumion is just way too slow.

Please add support for Quad-SLI and 26.000 rendernodes.

If you could combine this with the new DX12 Render-before-I-Animate plugin we'd be getting somewhere.

Oh, on a personal note, I'd also like Birds to build nests and termites should eat the wooden floors of my 3D houses.

I'd appriciate a PM if you have it done somewhere tomorrow.


That tesselated water and terrain from the Nvidia techdemo does look cool though Wink

You can already go to fullscreen. Just press CTRL+F11
