hello again, i post what im using so far, work in progress though and the screenshots were 1154*864 (or whatever it is) trying to get the game to look a little less sharp at the moment but no luck, just keeps crashing, by the way i found -devmode in your shortcut and editing the time of day in the console can give spectacular effects in game with HDR, plus you can slow down the rate which time passes, thats current CVARs.

give altering time of day a shot as well using -devmode in .exe, console in game and e_time_of_day=8.0 for example (8am) or something like 6.5 (6:30am) at sunrise
before i forget, avoid using r_TexturesStreaming=0 in warhead, causes serious crashing problems for me
