Well ive been digging abit deeper into this problem i get say with half life 2 and the f.e.a.r demo and for the last hour or so ive been messing around with the f.e.a.r demo with putting all settings to minimum(so it looks crap yes) to find obviously at minumum settings that there's no pauses at all which u would expect.
So bit by bit ive kept putting each setting upto maximum and to test kept reloading the start bit of the f.e.a.r demo when u get out of the car and turn right(the usual bit where it pauses horridly for me).
Ive found this..that i can put every setting upto maximum in the computer performance side of it which with this processor u would expect and it dosent pause at all in the menioned area or any other(was bliss playing it without pauses i must say..even though it was at crappy res etc..lol..)
Then i started maxing each of the gfx settings in fears settings and i found the one that really starts it to cause pausing badly round the first corner is video texture and texture resolution..as soon as these are set to medium or indeed high it gives me the pauses really bad but when these two are knocked back down to minimum it plays as smooth as buttermilk.
In half life 2 aswell ive personally found that knocking down "texture" to low the pauses and hitchies went away and indeed in battlefield 2 ive found that if i knock down texures to medium and not high i dont get the pause it usually gives a lot of users at the start of the map.
So in summary most of my games for some reason(especially with this setup which baffles me and it is optimised,tweaked and looked after) when textures/texture resolution is turned up to high 9/10 thats what i think gives me pauses and stutter probs in games..why?..i only wish i knew..and ive applied the memory tweaks at the top of this post aswell..if there's anymore to do with say speeding up texture transfer between the cpu and gfx card or anything along those lines plz point us in the right direction..this is just the one and only thing that really spoils my pc games considering the system i have.
Sorry about long post but there you go lol..
