Topic: What are Lumion's plans for full Windows 10 support?

[cleartech]

Hello.  We have a client with one Lumion 3D license.  They would like to purchase additional licenses; however, the lack of support for use of more than 2 GB video RAM in Windows 10 is holding them back.  Can you  tell us what your plans are to get to full Windows 10 compatibility and a (very rough) timeline?

Thanks very much!

Hi cleartech

I'm unable to give you an indication of where the upgrade to resolve the issues with Win 7 and DX9 is.  However, I can say that the developers are working solidly on it, and making good progress  .  Unfortunately, I can't give a timeframe at this stage.

Typo on the 2GB?
Please note that the Windows limitation is 4GB, so it only affect things where the scene requires in excess of 4GB.  If users have 2GB cards then that will be a first limitation which requires a hardware change.  We currently need to recommend users run Windows 7 (64 bit) until the issue is resolved.  Under Windows 7 there is no limitation.  Please refer: Why do you recommend Windows 7 instead of Windows 8 & 10?

I appreciate that running Windows 7 can be an issue in itself as some systems gets upgraded automatically by Microsoft, or it is not viable for the company.

Hi peterm

Thanks for the reply.  Thanks for the correction to 4 GB (I was working off a faulty biological memory module!). Glad to hear that progress is being made.  The real issue is that Windows 7 is becoming harder to support as checking for updates sometimes takes hours and sucks up background CPU cycles. This is Windows so updates are not optional!  The other factor is that we would like to take advantage of the "free" upgrade to Win 10 before it expires at the end of July.

is this still an issue for lumion 6.0. Does 6.0 still use directx 9? I remember not to long ago playing with lumion on a sister company's computer and they had a 6gb titan black with lumion and it showed all 6gb available in the fps doc in lumion?

Hi cleartech

 

Understood, yes appreciate the difficulty with Windows 7.  It's also a problem in that some Windows 7 users systems are auto-updating to Windows 10 even though the user has not set Windows to change OS.

There is a way to recover back to Windows 7 but most people are not aware of it.

Yes, July is not too far away now.

Hi scottofaz

Lumion v6.0/v6.3 uses DirectX 9.

If the Titan card with 6GB was on a PC with Windows 8+/10 then the Lumion Performance Monitor with FPS etc, would show 6GB.  That is, it is reporting what DirectX reports and so is correct, whereas for Windows 7 it (DirectX) was only able to report up to 4GB. 

On Windows 8+/10 the problem is that the operating system using DirectX 9 was limited (not in Windows 7), and so only the 4Gb was accessible to Lumion.  See further: Why do you recommend Windows 7 instead of Windows 8 & 10?
