Try increasing “Size of the virtual texture in tiles” ( mine is 65536 |16] ) and decreasing “size of each virtual texture tile” ( mine is 64 [0] )
Final resolution will still be 4MiTexels but will be divided in many smaller tiles.
It doesn’t solve the issue but it’s less noticable as, while tile updates are still as slow, more tiles are updated and fewer are not so the over visual is less bad.
Also I add to tick “enable adaptive page table”, both in the RVT texture settings and the “RVT sample” node settings in the material, to reduce time needed to update tiles.
