Hi, I am running Capture Atlas on two pc's (one laptop and one desktop) Both machines have the same file with the same render settings, the Laptop is getting 19/20 FPS but the desktop with the brand new GTX 1080 is only getting 7/8 FPS. I have updated the drivers on the 1080 to the latest versions but still no speed increase. PC specs are below.....Anyone have any suggestions.

Desktop PC

Processor - I7 3840 3.6GHZ

GPU - Geforce GTX1080

RAM- 32 GB DDR 3

OS - Win 7 64 Bit

Laptop

Processor - I7 4700MQ 2.6GHZ

GPU - Geforce GTX 780

RAM- 32 GB DDR 3

OS - Win 7 64 Bit

i seem to have resolved the issue by turning off various 3d objects an water jets, however ....... While my real time pre-viz is great, when i record a snapshot movie, that snapshot is very jerky and nothing like the real time viz. If i export a movie that too plays badly. What i have done is to turn off the 3d objects and water jets so only the lighting layer is visible (60 super sharpys) , this did not help so i deleted those items from the file so its just the lights and the snapshots work fine and so does the movie render. Do you have any solutions to this one ?

Hi,

It sounds like Capture is struggling to record the movie snapshot as it's visualizing the project at the same time. I would suggest reducing the rendering settings or the size of the live view while recording the movie snapshot. You could even record it with no view in Live mode.
