Resolume chooses onboard graphics card for playback

[Bogia]

Hello guys!

Lately I encountered a problem regarding Resolume's use of my graphics card ... I observed a stuttering and fps drop during the playback of my videos and checked the Option "Output -> Show Display and slice info". On my output monitor it says that resolume uses the onboard Intel HD4000 instead of my mobile nvidia GT 640m card. Even on my programm monitor (when I run a video in fullscreen) it states that the screen is using the onboard Intel card if the programm itself runs with the nvidia... awesome!
In the nvidia control panel I configured the driver to always use the nvidia card with resolume. The driver has a little icon in the systray which says that it is using the nvidia card when i'm running Resolume...
But when you run a video in full-screen it seems that another process is started (called Avenue Display, check the task manager). I guess, this process is not affected by the nvidia driver ... I tried to add this process manually but did not find it in the resolume install directory.
I have a gig on saturday which i was preparing for like 4 weeks ... Would be very glad if I could solve this problem till then so I can use the superior power of my GT 640m
:S

Any ideas anyone...? Perhaps you know how i could add the process 'Avenue Display' to my nvidia driver ... I just dont understand why the basic Avenue Process runs with my nvidia but the display does not ...

Regards

Can you try right-clicking the app and choosing to run with the NVidia card there?

I configured a cheapo laptop with similar specifications a few weeks ago and got it working quite successfully with Resolume. In order to get Resolume to use the gt640m there were three settings I changed in the Nvidia drivers. Note that these are the global settings, not application specific.

1. Make sure to set the gt640m as the primary renderer (can't remember exactly what this is called sorry but it sounds like you already did this)
2. Set threaded optimization to on. (not sure if this really helped but it seemed like it did so I left it on)
3. Set the power settings to prefer maximum performance (this step was crucial and is what made it work after a couple hours of fiddling)

And just soz ya know:
You cannot install the latest nvidia drivers unless the intel HD 4000 drivers are installed. Sounds like you've already got em but when I did this from a clean install I spent at least an hour trying to install the nvidia drivers before I figured that out.

Drivers for the mobile GPUs are kinda hard to find on the geforce website. Make sure to search under beta/legacy drivers to see all that they actually have available.

Use GPU-Z to see what the graphics cards are really doing, it's free and a great utility.

Good luck, let us know what happens.

You have a notebook with Nvidia Optimus which means the nvidia chipset goes phisyclly through the CPU.
It will always tell you you are using the HD4000 because it is going through it but it will use the GPU instead.
You can use GPU-z to see the utilization.
Use the Nvidia Control Panel and configure resolume.exe as "Maximum Performance"
Use latest drivers for both INTEL & NVIDIA.
I am using 680M with optimus without any problem, Nvidia GPU is always used.
