I recently upgraded from a Radeon HD 4650 to a HD 6670, and it appeared to work fine for a while until recently.
Somehow the textures in some games (Skyrim and SWToR) appear to be loading extremely slowly, causing the game to stutter terribly. In other games the card runs smoothly with no trouble (Saints Row: The Third and Space Marine)
I've solved the issue by doing a complete wipe of drivers, uninstalling them through the remove tool and Driver Sweeper.
But apparently the same issue has re-occured, only to be solved again by the same procedure.
I'm at a complete loss as to what could be the cause, any ideas?
you probably need to tweak the graphical settings, remove Antialiasing, lower texture graphics, because that gpu isn't too powerfull to handle those games (Skyrim and SWTOR) at high settings. probably tweaking the graphics will fix your issues.
I was starting to suspect a wonky PSU, seeing as I haven't got a high end unit, though I imagine that would cause the issue to occur constantly instead of just occasionally.
I'm no expert on this in anyway so it's just guesswork from my end.
I'm seeing distant geometry with textures as it appears normally, but the game just appears to stutter immensely until it has loaded the texture, after which it will run smoothly until I move onto a new area. (does that make sense?)
This is in Skyrim, by the way.
In SWToR the FPS drops immensely just by looking at the character selecting screen.
It might not even be a texture related problem, but I've reported it as I see it.
As for the DDR3 memory question, as far as I recall they both use the same yes.
