Hi all, I’ve had some success recently with the newest Intel drivers and wanted to share!! After my last thread (my old i7 machine), I upgraded to an i7-8700k and a stock version of W10 and I have yet to be able to get QSV to run without an error. Bummer. Not even once out of hundreds of encodes would QSV kick off. Where my old i7 would start and bomb out anywhere from 20-98% completion this new Intel chip won’t even get going. QSV is enabled and MCEBuddy is detecting it correctly but I get an error:
–ERROR: encqsv: MFXVideoENCODE_EncodeFrameAsync failed (-17)
That was with the drivers W10 installed (22.20.16.4758). Windows update shows no driver update available.
Yesterday I updated to the latest driver (22.20.16.4944 aka 15.65) since I had nothing to lose and the release notes say there’s been optimizations for the Intel Media SDK:
–Improved performance in video encoding for all codecs
–Optimized memory usage for HEVC encoding
So I gave it a shot and I know it’s only been 4 or 5 encodes since then but QSV is running flawless and thru completion (at a rate of 205 fps)!!
I could never get W10 to downgrade the Intel drivers to the versions suggested in the FAQ, so I’ll have to try this new version on my old PC too to see if things improve. Not sure it would as the updated drivers are really for the 6-8th gen Intel chips. Intel’s website isn’t very reliable as far as telling you which is the newest driver. I was on an older release driver 15.60 and that webpage said it was the latest release…which isn’t true since 15.65 is out.
Wondering if anyone having issues with their QSV/drivers and not being able to downgrade would mind trying the newest version?
