Sandy Bridge has an upper limit of 1920x1200 unfortunately, on Ivy Bridge and later it's something 4Kbounceplink said:Does QSV have an upper limit on resolution? I run in native 2560x1600 and when I try to use QSV in anything greater than downscaling to 1.50 (1706x1066) it pops up the qsvimpl invalid parameter error and crashes out.
I see; the issue with your iGPU not being logged by obs should be fixed. No idea what to do about the newer drivers though, but as long as it works with the older drivers … you are probably right on the random "fix"/incompatibility introduced by intel or Sandy Bridge class mainboards having wonky support for Ivy Bridge (graphics)ivannew2012 said:On win8, only igpu, 15.31.17 drivers, qsvimpl=,d3d9,1.4, dark stream on twitch and he says not supported format, log http://speedy.sh/jzmYE/2013-10-17-2031-07.log
Quick Sync is enabled, 4% cpu usage by OBS.exe. If qsv not been enabled cpu usage be like 80% because i choose slower preset in x264 encoder.
Now try Win7 with extra settings...
Same result, maybe intel "fix" something, like they fix no overclock on chipset b85. My motherboard is for sandy bridge, but processor is on ivy-bridge. It's just not qualified guesses. Maybe in future it will work for me.
For now latest drivers(15.31.17) don't work for me and it's not a problem, use older one without issues.
