WIP Track descriptor usage between frames #290

Closed zakorgy closed 5 years ago

zakorgy commented 5 years ago

This is the next step toward reducing the number of descriptor pools, since we will not need a pool per frame anymore. By tracking which descriptor bound to which frame we can reuse descriptor sets from the same pool for different frames: If we have a descriptor set which is good for our needs we can check if it's available to use or it's still used in a previous frame and we need to create a new one.

The current solution is only applied to one descriptor group (per draw descriptor sets), but we can easily apply it to the other groups as well.

I close this because #291 contains this solution as well.
