After tweaking to death I decided the optimal image quality vs performance setting for me is; Resolution: 1024x768 Settings: All Very High/No shadows Framerate: 30-40 My OS is Windows Vista Ultimate x64. Shadows and 1280x1024 resolution make a big difference, but the extra 15fps with them turned off finds that 30fps sweet spot to enjoy the game. Alternatively I could go with the recommended All high/1280x1024 but thats like changing from "Real" to "Videogame" because Very high really is that great! I've suffered from extremely frustrating stuttering here and there. The stuttering means 5 seconds of 30-40fps followed by 1 second of waiting and so on. It appears to be completely random whether or not it occurs bar a few variables; When an explosion happens (grenade, barrels, whatever) Turning 90degrees+ very quickly (loading new scenery...) Firing a weapon (not melee attacks though) Playing a new level (sometimes I restart my computer and the level will work fine afterward, like the cache for the previous level has been purged and the memory is available again...) I did notice the game started working extremely smooth after I stopped playing it with fraps running (not recording, just displaying Frames per second) I have also defragmented/closed Windows Sidebar MSN messenger to see if it prevents stuttering but its still a random occurance. I'm looking forward to newer drivers/patch support from Crytek to see how things are after that TOO MUCH DETAIL? READ FROM HERE And I've made this thread to ask these key questions: What are your Videocard/Settings/FPS - do you get stuttering issues? (I'd like to see what ATI & Nvidia owners have to say) Have you overclocked any components and what impacts does this have on the game? (Positive/negative) What O/S do you use? Are the stutters a Vista exclusive? Does 4gb RAM prevent the stutters? (I tried a friends PC5300 2gb kit with my pc6400 2gb kit and while loading times improved noticably, there wasn't any ingame improvements) and just for fun... BEEP!BEEP! thats all folks!
