Topic: Lumion 5 EDU doesn't recognize Geforce GTX 860M

[Pseudomonas]

Hi,

I just got my license for the Lumion 5 educational version.
I am running the software on my Acer Aspire V15 Nitro BE Laptop:

Intel Core i7
128GB SSD + 1TB HDD
8GB DDR3 RAM
Geforce GTX 860M (Latest Driver 347.09)
Windows 7 Professional

Unfortunately Lumion always chooses the Intel chip graphic to work with. I tried to force Lumion to run on the NVIDIA Card within the NVIDIA Driver Menue, but with no result.

Can you help me out?

Thank you!

I just tried to reinstall Lumion. During the installation there is an error message:

Unable to execute file:

c:\program files\Lumion5.0\Redist\vcredist_x64.exe

create process failed; code 5.
Access denied.

Hi Pseudomonas, the benchmark reports the primary graphics card, even if the Nvidia card is used during the benchmark process. Please read this FAQ post for more information.

Regarding the Lumion benchmark score your graphics card is getting, it seems to be correct. For comparison, the 860M only gets 1705 Passmark Points. This is only a few points more than the 1500 points that are required for simple scenes in Lumion.

For better performance and faster render times, I would strongly recommend that you upgrade to a PC with a more powerful graphics card.

In other words, there is no need to uninstall Lumion. The installation error suggests that something on your PC is preventing Lumion from installing the Microsoft Visual Studio redistributable files that are required when running Lumion. You will have to try to turn off any software that might be causing this problem on your PC, e.g. anti-virus software.

Hi Morten,

thank you for your response. I don't think that Lumion uses the Geforce GTX 860M, although the benchmark states that it uses the Intel HD graphic. I just compared it to my Desktop PC, which has a Geforce GTX 750 Ti OC. The Desktop-750 Ti and the 860M should perform more or less equal, but this is not case. Since the score with my Desktop-Pc and the 750 Ti is so much better than the score with my Laptop and the 860M, I am sure my Laptop Lumion uses the Intel graphics instead of the nvida graphics. Or did I misunderstand you and the displayed result really is for the Intel HD graphics, while the result for the 860M is not displayed.


Thank you for your support,
best regards,
and sorry for mistakes in the language, i am a student from germany

Hi Pseudomonas, the 750 TI vs 860M Lumion benchmark scores correlate almost exactly with the Passmark scores for those graphics cards, i.e. the 750 TI is about twice as fast as the 860M. If Lumion really was using the Intel HD card you would quickly notice it as certain things don't work correctly with Intel HD cards, especially when rendering Movie effects.

I know you were expecting the 860M to get a better score but unfortunately most laptop graphics cards are not really suitable for creating anything other than simple scenes in Lumion.

Hello. Sry to interupt i realised u said something about gtx 860M is not good for lumion(witch is identical in perf with 770M witch is identical at chip with 670MX witch i got) .... he put benchmark scores of 750ti  > 8820 points. U said 750ti is twice as fast. Is not true, i oc'ed mi 670mx (600/1400 to 760/2400 or harder 850/2400 ;i will try 1000/2400 after bios mood; at 1000 mi scores should be 12000 points or more) at 850clock speed i got 8640 gpu points .... 860M hits 7900 or 8100 points it differs....   i atached an image of mi performance of laptop, i can render movies max quality 1second = 5minutes > efects on or off same render time don't differ... ps i got lumion edu dunno where license is aniway if i find i post but is edu v, i got it with other acc, witch ) i lost pw of it anyway

fps were taken in lumion > examples > villa > without moving camera witch is set on building to view ...

[MatrAguNa]

wanted to ask, lumion engine is the same with cry engine? or they work the same, since i got 24 fps in lumion and Crysis 3 (cryengine). anyway last question: when will lumion get indirect lighting as vray?... hyperlighting from lumion 5 is not realistic, is better but still unreal.... i found a way to fake the effect by puting omnilight on eatch lighttrail.... example: for 2 spot light and i want 3 light reflection ,i need 6 lights (2 spots and 4 omnilights) to simulate the bounce effect. looks preety realistic but takes very much time to think of light reflection and set light amount power etc... still w8ing for lumion indirect light as vrai has.

[MatrAguNa]

look at gpuboss comparison's why does lumion score differ... i think that benchmark doesn't show correct

Hi MatrAguNa, I'd be grateful if you could forward your name, the institution/university and the department where you are studying to morten [at] act-3d.com and peterm [at] act-3d.com, so we can verify that everything is ok.

Thanks in advance.
