Comments on the 285GTX and the Limiter

Question

I ask if you have the time and are willing, please post your experiences or feedback with the 285GTX and the limiter whether positive or negative. I will forward to the appropriate parties This is not a official Adobe request or anything incase any are wondering.

Answer 1

Thank you for the feedback. The limiter comes into play on the 285GTX when you add effects to a 4th layer or higher video and leave the tracks active. The yellow line above your sequence will turn red indicating that the effects for that layer will be processed by the CPU and you will have to render out those effects to export them with the sequence. If you monitor your CPU usage once you add effects to a 4th layer or higher, you will see it increases far more for that layer than it did for the previous 3 layers. Basically what the limiter does is force you to render your timeline if you have effects beyond the first 3 layers and increases CPU usage allot more for any effects beyond the 3rd layer. This requires those projects to take more time due to rendering the effects on those layers. For many that may not be an issue but for those with tight deadlines it will be. If you monitor your GPU usage while playing back 3 layers with several effects, you will see the 285GTX is not being pushed hard with just 3 layers. It is not based on the codec of the material. AVCHD and R3D had the same limitation with regards to effects processing and the limiter.
My request for feedback is to determine if most people are barely pushing their 285GTX cards with 3 layers. Also it is to determine if you would purchase a Quadro card due to the limiter.I will forward this information to our contacts at Nvidia and Adobe to show them the limiter is completely uncalled for. That is the only way we are going to get this changed now or with the Fermi Geforce cards.
