Well, i installed portal on my P.C, and i know my computer can run it because Canyourunit.com says i could (Then again i dont know if its true or not) So, i go to play it, i set everything on low since well my computer isnt THAT great. and i load the first level, and everythings all cool until it starts counting down to the very first portal. 5. . . 4 . . . 3 . . . 2 . . . 1 . . . And then an orange portal is made, now. heres when it crashes, i cant look at the portal AT ALL. if i look at the portal, my computer freezes, so i try entering backwards! SUCCESS! until i see the blue portal, then it crashes, so i look at an angle so i would be able to see any portals. SUCCESS! Until i pass through the orange portal and see a wall and it just crashes! So i need someones help to try and fix it. Does anyone know how to make it so i can atleast go through and see the first level?
