I'm using quicksync via 3rd party software (rigaya QSVEnc) website here:- https://github.com/rigaya/QSVEnc
This 3rd party program has been used for many years in the global community for use in QuickSync tasks. I have been using this program for several years and have encoded hundreds of videos in that time. Never seen the target usage changed by the driver like this.
The issue I have is that the "target usage" or "TU" is being changed by the intel graphics driver from 1 to 2 (from "Best" to "Higher") for no obvious reason. I have never seen this before. Version of graphics driver is latest (32.0.101.8136). Command script is shown below. I have highlighted in bold italics the relevant parts:-

Thanks very much for getting back so quickly.
I'll answer your questions and attach the SSU data.
- When did this behavior start, and what was your previous Intel graphics driver version? New laptop - so started from new. Driver version unchanged.
- Does the override happen immediately at the start of encoding or during the encoding process? Happens at the start of encoding process.
- Can you reproduce this issue with a completely different video file? Yes - all files affected.
- Does the issue occur in other QuickSync applications or only in QSVEnc? Yes - I also have Handbrake v1.9.2 installed and that does the same thing.
I should state that (for myself) this is a minor issue. There is very little difference between target usage 1 and 2 as far as output quality is concerned.

Just some more info.
Rigaya whose software is used, pointed out to me that he has an Intel Arc B580 card and for him the number of "levels" has been reduced from 7 to 4 for HEVC. I can confirm the same happens on the Intel 130V GPU on my laptop.
Normally each of the 7 levels are independent and can be chosen separately. Now what is seen is the following:-
1=Best changed to level 2 by driver
2=Higher changed to level 2 by driver
3=High changed to level 4 by driver
4=Balanced changed to level 4 by driver
5=Fast changed to level 4 by driver
6=Faster unchanged
7=Fastest unchanged
I should probaly change my comment about this being a minor issue. That was because I now use AV1 encoding primarily now. As stated, AV1 encoding does keep the 7 levels separate. HEVC encoding is where this merging of levels is occurring. I would think this is a more serious issue as HEVC is extremely popular.
Hi Mark62,
Thank you for the feedback. I am currently trying to reproduce the issue that you're currently experiencing. I will be updating you as soon as possible. Thank you for your patience and cooperation.
