Hi, I installed Doom 3 on my two footer, and on max resolution 1900 x 1200 it plays well, but not 100% perfect, for example... When beam with my flashlight in smokey places, the framerate drops and it stutters until I am past the smoke, then it gets better again. With the console I used the FPS command and in the right top corner it show 60fps in non crowded places and 26fps in crowded places. but it never feels like the framerate is that high... I have used High Quality setting, I tried shadows on/of but it doesnt seem to matter much. My system is updated to 10.4.8, and Doom to Version 1.3 Does anybody have a idea or suggestion about this? Thanks !
