Mmmm, i dont think so, in lfs option detect and use the HD2600, other games too, so i dont think that the issue, also some time back i'be tested with the onboard video and do the same things...
Also is something that is programed in each mobo, when you insert a AGP / PCI video card automaticaly the onbard vc is disable. so i highly doubt that is the problem
Drivers, i dont think so, i'm using 10.10AGP hot fix, i'be tested 10.10b / 10.12 / 11.00 / 11.10 / 11.11 and so on, even i'be tryed omega drivers and the problem persist
BEFORE THE PROBLEM
I was running LFS as usual on cargame in a open track with 30 cars ahead i was having a wonderfull 20-30 at the start after the first lap 40-60 solids FPS
Videos on yutube on 720p full screen perfect and no choppy at all, videos on X player in 1080p with perfect playback
Others games like crysis 2 o oblivion or GTR2 or GRID working perfectly
AFTER THE PROBLEM
In LFS on Open config ( Like i told above ) barely 2 - 6 and and after 1 lap 10 - 20 fps
Videos on yutube barely can watch on 360p on full screen, Videos on X player barely on 480p and . AVI
Other games Damn can't run shit now..., now the pc looks like a p4 running at 1ghz lol
I'be tested the ram's and VC on other pc and works perfectly, I'be reeinstaled the SO ( Full HDD Format ) and the problem persist, so i discard a software problem
Anyway, what could it be?, the CPU or the mobo ( Some BUS ), any idea?
Well a S7 have a gear box of 5 speed ( Some case 4 ) But 3???, old schools cars like the Mercury cougar 68 / Dodge challenger R/T / others have 3 speeds... ( Of course as a vanilla car )
