I don't get how you compare a large company like Ubisoft to HTC. Im sure if HTC had 15 offices the graphics would be updated and wed have all the bells and whistles. On top of that Il-2 has many more people out the creating mods. Granted with the declining player base maybe it is time to do something new like selkl the AH license to SOE or EA well get much better graphics and a War Thunder flight model would you like that? Honestly how many employees do you think HTC has?
Enough to update graphics just a tad every so often? I am not saying we need game breaking updates every 3 months, however, I think a
moderate update every
other year
or so to the graphics would be justified.
I remember one very slight update to the graphics, but I think that was at least a year ago, and it wasn't anything special other than what appeared to be a few slight texture redesigns or something IIRC.
Wasn't the last major graphics update from AH1-AH2? (Actual question, I do not know)
