In that case you better dust off your Win98 and AoD installation...
I'm quite satisfied with SH5 and even with SH4 which you have discard so easily...Should I remind you that even many hardcore SH3 players have found SH4, in combination with various Atlantic/Pacific mods, very enjoyable?
I guess you don't have the same opinion (probably
rage-quit after 45 min in SH4 or so

)...
Something's telling me that you are not quite satisfied with SH3 as well...
Anyway, most of your mentioned SH5 remarks could be easily fixed with few additional mods/tweaks.
Normally, people will usually ask for help/advice until they are able to set up game files/options to their liking , without
trashing someone else hard work, but offering any help in this case would be utterly pointless...
