I'm running a 2500K at 4.2 with 2X560 GTX T1 (1GB) cards and 8 GB ram and a normal STA3 HD: I'm still seeing texture popping post patch along with all the CFG tweaks ergo ID Tech 5 is shit.
We get these nice landscapes with no-quality texture popping. I can live with the texture artifacting due to texture compression, but the popping must cease. If they want to patch the game outside of the popping problem then they must add some proper dynamic lighting/shadows + adjustable motion blur. They can also re-work the skin quality of the models, the people's skin look very cartoony and not flesh like.
