There should be almost no impact to “runtime” performance. Join time performance will be impacted because we can fetching more assets and there is more “composition” happening. Once the clothing item is deformed at the time of “wearing” an item, the performance should be on par with the current real-time performance of avatars. We are working on further reducing join time performance… so stay tuned.
Distance should’ve no effect on the clothing detail currently, since we do not create LOD for avatars at this time. We are working on avatar LoD that would eventually both improve performance and adjust fidelity based on distance. Stay tuned.
