Hi everyone,<br> <br> Quick question; Have any of you tnt/tnt2 owners had succes in enabling volumetric fog option in Unreal Tournament.<br> In d3d rendering this eats frames. I remember when I used software rendering with my old ati rage pro card, volumetric lighting had no speed penalty.<br> I would like to enable it but it comes with a cost.<br> <br> Does volumetric lighting data get precached? ANd where comes the slowdown from? Does it hit cpu or video card?<br>
