I also find it impossible to spot in medium to short ranges. At long distance I clearly see the dots but at 3 miles the plane becomes transparent and disappears only to partially appear at half a mile with greenish frame. this phenomena persist in all FSR/nis/none modes. I've been using the none MT dcs for that reason the last week. Hope it will get resoled in the future.
I'm using reverb g2 with a 6900xt on a Ryzen 5900x.
