Fix white Jug, and more nice looking skins would help too. The above picture is a reskin from Janes WW2 which is a 4 year old game isn't it?
The frame hit difference wasn't noticed, I have a P1.2, 250RAM, GF2.
Anyway, at more than 200y a plane in AH is just black, at 400y, you can't even tell what type of plane it is without using the zoom.
I honestly don't care much about how the scenery looks, actuall AH ground scenery is good enought for me now. But the planes, I'm sorry to say, even the new ones, don't impress me much in their skining. I know it's just a question of personal preference, but I far as I'm concerned, my immersion factor is higher in a P47 who looks like that than in the AH one. The frame rate issue should not be that much either, I didn't noticed any in Janes WW2 and I don't have a ubber config.
Lastly, when I'm 150y in a bandit 6, I think I should be able to see him big enought to see the pilot color eyes. I tried it at Chino, I standed at about 200y from their WBs, and you could see a lot of details, but I guess that's the advantage of the human eye over a computer screen.
My 2cts

I wanted to say of this for a long time now, finally did it ... wohoo. I love AH, but the graphics are aging pretty bad, there's probably nothing they can do about it, but didn't heart to tell them my thoughts.
