Friends, how King of the road game hasn't section put question here. Playing King of Road on P4, agp ati 3450 graphic card connection, windows xp, no problem with textures.
Playing game with Intel quadcore, pci-e nvidia gt 440 graphic card, windows xp os begins problem with textures. Part of road, background around roads and building dissapear of screen. Not canning to play it well. Rarely playing with oldest Hard Truck II doesn't present textures problem on Intel quadcore computer.
Why with windows xp, textures well on old P4 and bad textures from Intel quadcore computer?. Thanks, if anyone gives me answer to clarify this problem.
