i upgraded video card gtx 580 gtx 680. @ first, pp did not recognize card , had manually add config(?) file.
my problem pp cs6 makes poor use of new card. render times slower before. when check gpu usage, keeps jumping , down. never reaches above 40 odd percent.
am doing wrong?
hi,
i've running gtx 670 here , works fine...
1. because of system design of gtx 580 , gtx 680 don't see dramatic speed improvements upgrade... (gtx 580 has less shaders working 2x speed of ones in 680)
the gtx 6xx series great cards , have lot of new things offer... need less power , don't hot 5xx series - support 4 displays per card , have other clever enhancements...
but 6xx series don't outperform 5xx in terms of cuda performance - , second question is: need raw renderpower of card???
think why nvidia marketing slow old gpu processors on quadro line of cards "ideal solution" pp?
because more important have drivers , fast video ram have maximum count of cuda cores running...
to gtx 680 limit have add lots of cuda accelerated effects on multiple hd layers , feed video ultrafast raid or ssd's because graphics card fast rest of system...
--> thing slower old card - shouldn't be...
