This is a request for an optional setting within the region/estate tab in the viewer to increase the terrain resolution per meter. From what I can find, the max polygon resolution of SL terrain is 2 triangles per square meter (A vertex every meter, 257 vertices in each direction) and has remained so since 2004. The option to increase this even slightly (X2=4 tris per meter) would make a tremendous difference in the terraforming capabilities. I suggest this as a regional option for official and 3rd party viewers, rather than standardizing it across the whole grid or trying to implement it for sub-region/parcel level, browser or mobile, as it seems like that would be the least impactful method on performance across all delivery methods. Additionally, this could coincide with PBR terrain implementation; Adding this to features such as tri-planar mapping, possibly height and/or occlusion mapping would modernize the seriously out of date terrain quality within SL.
