This is me fighting of the Hell Knight demons in Delta Labs Sector 4. I have the graphics enhancement mod Sikkmod installed. It gives DOOM 3 Soft Shadows, SSAO(Screen Space Ambient Occlusion), DOF(Depth Of Field), Motion Blur, HDR(High Dynamic Range), Bloom and a lot more.
I have Soft Shadows and SSAO turned off because it makes the game lag too much, perhaps when i get a better graphics card I can turn it on and make a video of it to show you all what it looks like.
I also converted all DOOM 3 textures up to maximum High resolution 2048x2048 pixels resolution. Hope you like my video.

I'm also using Monoxeads High Resolution Textures for DOOM 3 that changes some of the textures in the game including the textures in Mars City. You can find his High Resolution Textures here http://doom3-hr.com/Main_Eng.html
