Olds: I have a 660Ti too (MSI.) On certain maps and and at certain bases my frps drop, sometimes considerably. I also get big drops when the furball starts to get near ~50 or greater in immediate vicinity. I am however running a somewhat older machine with this new card. I turn off all the unnecessary programs I can find. I turn AVG av off, but it still keeps running 3 programs even when "disabled." I don't use shadows and no ground clutter either, yet there is no way I could keep steady frps around 80 ppl. My background programs running total ~44, and my CPU usage is usually in the 2-5% range (I know Skuzzy recommends that it be lower and near a steady zero if possible.) What do you think the difference is?
I should note to the above though, that the majority of the time my frps are steady at the said settings.
Also, what does the set field of view setting correspond to?
What is your CPU, you never stated it. For one if its an AMD CPU you are in some trouble as a friend of mine has a fx-8350 8 core AMD and my quad core 4 years older i5 2500k still beats him in FPS.
Also my CPU usage when i normally play is around 10-15% as I have pandora and multiple tabs of web browser open.
The game tried to fine the "best" FOV for me but I like wider FOV in this game for better SA (flying with mouse and keyboard its harder to keep SA high...) Also thats another thing, generally the higher the FOV the bigger the FPS drop... How ever this isn't really a factor anymore.
EDIT: What model is your 660ti? is it 1gb or 2gb/higher
