Hi,

technically the drivers are pretty similar, the main difference is, that "Game Ready" drivers are mainly tested with the big computer games, "Studio drivers" are tested with Adobe software and other "Creator" applications.

For vMix I would recommend using the "Studio driver", this is ok. A few more points to this:

1. Take is easy with updating the nVidia driver, at least as fas as vMix is concerned. I'll update nVidia drivers 2 or 3 times a years. Thats fine.
   
2. If your graphics card is pretty new, it might be useful to update more often, until this particular card has had some time to have all the driver issues fixed - if there are any at all.
   
3. Be careful to remove the "GForce Experience" software package. This is more to make things easier for causal users, but sometimes gets in the way if you need more control.
   
4. The updates that work together are Windows Updates, vMix Updates, nVidia Updates and videocard updates (aka Blackmagic). Depending on your setup, it is a good idea to plan an update day every now and than. Do the Windows updates, the nVidia update and the vMix update. If your videocard driver is working ok, leave it alone, unless it is getting older than a year or so.
   
5. When updating videocard drivers, take the time to test all In and Out (SDI/HDMI) connectors throughout.
   
6. Before causally updating vMix, please make sure you read the Release notes and decide if you need to update just two hours before a live show. (I would not recommend it...)
   
   

Hope this helps,

Christian

Actually, vMix recommends using "Game Ready" drivers, they are geared more towards processing "LIVE" or "real-time" video compared to "Studio" drivers which are optimized for processing saved data and rendering special effects.
(but as noted above, there is not a lot of difference between them and both will still work with vMix)

Thanks Greg,

apparently there is no big difference, but I will change this in my training documents. Did you ever notice a difference somewhere / under certain conditions?

Do you know what kind of processing vMix offloads to the GPU ? It is still a bit of a mystery for me. I guess h.264 decoding runs on the GPU, maybe browser rendering in the Chrome engine, but what about the SpeedHQ codec from NDI sources? I am under the impression that this is handled by special CPU based code, but I might be wrong.

Thanks,

Christian
