DWM crap performance


vinifera

Recommended Posts

I'm bit lost

I have good machine to run win7

CPU dual core AMD Athlon (X2 5050e)

3 GB ddr2 RAM

and high end GPU GeForce 7950 GT

yet with DWM on, explorer takes 2 secs to open

browsing through folders lags

going into pictures folders and enabling thumbnails takes up to 15 seconds to show them

with DWM off, everything is instant, 1 to 2 seconds

shouldn't the effect be reversed ?

shouldn't the system with GPU usage (which is superior than CPU) be faster ?

(at least in drawing/showing things)

without doing all that stuff :P

could it be because my GPU is direct x 9

and I remember that Vista's DWM (longhorn) was actually dx9

but since win7 emulates dx9 unlike 10 and 11

cant it be coz of my gpu being dx9 and win7 emulation of it ?

I would recommend the OP get an XPerf trace, otherwise all we're doing here is guessing. A 7950 isn't the greatest card, but in the Vista days it was capable of getting a 5.9 WEI score, depending on how much vRAM was in the card and what it was clocked at. DWM should run fine on that card on a single monitor with a resolution of 1920x1200 or less, honestly.
