Performance and Stability on a system with hardware acceleration.

I am curious if there will be any optimization for systems that support acceleration. I have a Spectre x360 I5 12 gig 520gb ssd and 32 gb of optane memory. To say this laptop is fast or should be is well yeah. I love the thing and just picked it up. Imagine my surprise when, after installing Logos 9 on the laptop I found that the program actually works better on my 2016 dell xps 9550. The program was completely useless and I had to do some major digging to find a script that would deactivate hardware acceleration for Logos in order to restore functionality. Once the script ran everything was fine, however it's not really something that makes sense. Is there any process in place to optimize for pc's that have the new technology that makes them more responsive etc.

I have 16 gb of fast ram, ssd drive and Logos runs great. I also have a 8 gb 500 gb hard drive and Logos runs slower.

I think Logos is a memory hog, meaning it loads a lot into ram. But I would not think that the ram could be so fast as to affect the working of Logos. The 32 gb you have should make Logos sing "Hallelujah".

Having said that.... sounds like a machine like yours is a gaming machine. And I know they do some special video tricks to display things faster.

For example.... on my main system... with 2 monitors.... I load Logos ... my ram usage will shoot up to about 6.0 to 7.2 gb depending on which layout I open. I do load other things, other than Logos... which increases my ram usage. 16 gb is where Logos seems to be comfortable.

Hi Aaron

I don't know if https://support.logos.com/hc/en-us/articles/360052821231-Display-problems-on-11th-gen-Intel-processors-with-Iris-Xe is the article you mentioned.

If not, it might provide some context regarding what is happening (assuming you have an X11 processor)

I agree!

WPF is the user interface technology Logos 9 uses to display the program. There's an as-yet-unacknowledged bug (most likely in Intel's graphics drivers) that makes WPF hardware acceleration run unusably slowly. The only workaround is to use software rendering instead of hardware acceleration (which is the script you found).

Modern fast CPUs are probably entirely capable of handling Logos' graphical needs without hardware acceleration, so I wouldn't worry about the program being slowed down by disabling it.

FWIW, you can read about other software developers encountering this problem here: https://github.com/dotnet/wpf/issues/3817. There's not much we (Faithlife) can do; it's up to Intel (and/or Microsoft) to diagnose and fix the incompatibility / performance problem.

Is this a universal script that would deactivate hardware acceleration on any computer? Just needing to remember this when I get a new system. Is this script shareable? Can you post the steps you took to deactivate hardware acceleration or do you just need to run the script?

Sure let me dig it back up. It was a pretty easy thing to run. You just open a cmd prompt and paste the script I found. I'm super comfortable with command line functions. I'll find the information and link to it.

Display problems on 11th gen Intel processors with Iris Xe – Logos Help Center

It's actually in the LOGOS help center.

Just be aware it only applies to this issue with Windows programs that use WPF (e.g. Logos) on the latest Intel Gen 11 processors with integrated graphics. It isn't needed for Gen 10 and earlier, and it doesn't affect acceleration for other programs.

Dave, I just want to make sure I understand your warning. This script is meant for deactivating hardware acceleration in computers running Gen 11 processors only. That is what I am understanding. I asked because my next computer will probably have the Gen 11 processor and I wanted to have this information in hand for that moment.

Yes.
