Is my Intel graphics driver up to date?

if you're curious.) Even though the i5 user does not have the problem.
So we're still looking, although I'd have thought the chipset driver low
on the list of possible causes?

Did you read my post yesterday reporting that I had installed the latest
driver?

Twas in another subthread, missed it, sorry.

Although both you and your friend are using Windows 10, are you both
using the 64-bit version of Windows 10?

Yep.

"... a native 64-bit video-editing program"

http://www.magix.com/us/movie-edit-pro/premium/
"You require a 64-bit version of one the following operating systems:
Windows 10, 8, 7"

You'd expect a 64-bit only program's installer to NOT allow its install
on a 32-bit version of Windows.

As to your original topic, you now probably have the latest available
driver. No, it may not be listed by Intel using the same version as for
the package of driver files. For example, the video package version
shown my AMD Catalyst and Device Manager is 15.20.1062.1004. However,
looking at the versions of the actual driver files show varying versions
(aka file versions, not package versions) only some of which match on
the package version. So it depends on which version you are looking at:
the package version (fileset) or the file version(s).

"The Core i7 features quad-cores with Hyper-Threading enabled and
Intel’s HD Graphics 530 solution. The Core i5 family offers quad-cores
without Hyper-Threading, and either HD Graphics 530 or 510 GPUs."

So the difference is whether or not there is hyperthreading and which
video controller is included on the chip. I had assumed you (i7) and
your buddy (i5) had the same video driver. Maybe not if he has an i5
with the HD 510 video controller.

If hyperthreading is the differentiating factor then maybe you disabling
it for your i7 might show if the Magix program then works okay. Maybe
Magix doesn't know how to handle virtual cores. Users have complained
that enabling hyperthreading results in BSODs or unstable systems
(probably due to a defective CPU) or even decreased performance for
multi-threaded processes (e.g., [M]SQL) when compared with
hyperthreading off. There can be racing problems or deadlocks in code
with hyperthreading (not a defect of the processor but in the code, like
not handling race conditions between threads). Thread stalling is
another problem with hyperthreading. I've seen some forum posts where
users complained that Magix did not use all cores in the multi-core
processor and also did not use hyperthreading. To me, hyperthreading is
like GPU acceleration in web browsers: sometimes helps but if not then
disable it. See https://en.wikipedia.org/wiki/Hyper-threading.

Some users report that stutter disappears after disabling
hyperthreading:

Maybe disabling the i7's extra features so it has only those in the i5
will get Magix to operate properly.

"Hyper-Threading Technology cannot have performance expectations
equivalent to that of multi-processing where all the processor resources
are replicated."

So reports from users that performance was worse with hyperthreading
enabled is even supported in Intel's description. Simulated hardware
isn't as fast as real hardware.

If it's a driver issue, you might have to test prior versions of the
driver for your CPU (i7) to see if one works. As I mentioned, the
latest driver is not necessarily the best one. For some programs
(games), I had to find the latest prior driver that still worked with
them. The latest video driver wasn't the best one and sometimes the
worst one.

Just to be sure, are you you (i7) and your friend (i5) using the HD
graphics controller within the CPU? Or might your friend have a video
card? The embedded Intel video graphics is particularly strong in the
graphics arena. Performance of CPU-embedded graphics is very low.

For graphics editing, I would think you would want something better than
what is essentially a backup GPU: you revert back to it when your video
card dies and until you get a replacement.

Thanks, appreciate the suggestions. I'll discuss with others in the
context of this HDR problem in the MEP forum.
