I had reached an "almost" satisfactory setup, eliminating most blurries problems during my single player flights, but I took part in a MP session yesterday and the blurries were back.
Does this mean that the additional load on the system brought by the network session and the other planes rendering lowered the time slice allowed for texture drawing, bringing back the blurries? In other words, have I reached my system's limit?
Would you identify my mere 128 MB VRAM as the main culprit?
