hi. i am new to perpetuum - but long time, avid *nix user, and admin.
i find the same issue running on older core2duo/geforce 8600gt-m based laptop running ubuntu 10.04, and wine1.3 - canonical nvidia dist, current.
i think ente is onto it... im going to play around with this pixmap cache thing, and see how it goes.(had problems with other games too)
i dont see why this game can't keep it's gold rating - it runs flawlessly under wine... (except for the map thing) in fact i have found it faster and more stable than under windows.
oh and btw celebro... 11.10 and 10.10 sucks my b**** - unreliable, buggy, not to mention too many changes... u r way better off waiting for the next LTS - and oh umm perp wants their game to run under linux so i think they WILL fix it either that or there will be a patch developed by one of us to fix the problem so windows fanboy
p.s. to the devs of Perp - THIS GAME IS GORGEOUS thankyou for blessing me with such a well developed, constantly expanding game.
