Another item to consider here..................
1. How many have the checkbox checked for "Disable ground clutter when in flight" vs others having this box unchecked within the game settings?
This setting was put in back in the AHI\AHII days to help out weaker vid cards by disabling the game to draw\render ground objects (read marston matting here, but other ground objects as well) when in aircraft that is off the ground above a certain height (read distance) to reduce the graphics load on the vid card by DESIGN as when you're flying the perceived importance of VIEWING ground objects was minimal at best. Remember the main advent for AH's creation\development was FLIGHT....................
Nowadays w\ the advent of much more powerful graphics cards some may not have this checkbox checked (not checked in game by default) thus the game (the vid card as well) will continue to draw & render ground objects regardless of the altitude (read height or distance) reached so it is feasible that at some distance the drawing\rendering of these ground objects (read the marston matting) along the visual line of sight will reach a point where the object tiling will morph due to draw\render limits into this pattern due to, in part, the improved game graphics now (along w\ the advent of ground gameplay where sharper, more refined ground graphics are more of a priority) vs older versions of the game but also due to how well the vid card's driver\GPU ability to draw\render the ground object (read fidelity here), especially at long viewing distances.....without creating this effect.............. Remember I said that the game client appears to not be coded to apply anisotropic filtering which would help to maintain the ground object's graphic tiling symmetry across the maximum viewing distance coded (whatever this distance is set) within the game's code for the game's graphics engine.
My read is this issue is also showing up on users that don't have this checkbox checked in game (like myself, but for other reasons). When primarily on the ground or flying at fairly low alts this isn't much of an issue but those who fly at higher\high alts w\ this checkbox unchecked are susceptible to seeing this happening due to this simple fact. Also my read is that this issue is also more related to those using the Dx11 vers vs those using the Dx9 vers due to the differences that Dx11 may bring to application in drawing\rendering ground objects vs Dx9....but I could be wrong.
So in closing the game graphics code doesn't have to be "broken" for this to occur...
.
I'm putting this out here due to the fact that I haven't noted of anyone else posting about this in this thread...
Something else to consider as well.
