Using Fidelizer with Intel’s efficient core investigation

I received report about Fidelizer causing very slow performance on computer and after inquiring about his computer’s specs, I found out he’s using modern Intel processor with efficient core.

By default configuration, it shouldn’t slow down his computer with recent changes to handle non-audio process with more processors but since I have no experience with Intel’s processor with efficient core myself, I bought one to investigate.

 

Fidelizer - NUC

 

This MSI Cubi 5 has Intel Core i3-1215U processor. It has 2 physical cores and 4 efficient cores with 8 total threads including 2 logical cores. I assembled this NUC with good quality parts and setup Windows 11 to test since most modern PCs start to adopt Windows 11 now.

 

After initial setup, I found some issues related to Teamviewer 11 in Windows 11 that fails to work after applying Fidelizer Pro at maximum user level. I’ve applied internal fixes now and will release an official update later after investigation. For now, let’s see how Fidelizer handling non-audio process.

 

Fidelizer - Default Purist configuration

 

It looks like Fidelizer doesn’t detect hyper threading function on this computer. Since processor design is changed from having logical cores at double amount, I’ll revise hyper-threading detection in next update to improve performance with efficient cores.

As you can see, only CPU0 is not used in non-audio process. CPU2 and CPU4 shouldn’t be picked too if hyper-threading is active but this should confirm that Purist user level with default configuration shouldn’t affect system performance being so slow.

Now, let’s check how core affinity works after picking “Enforce non-audio process to use only one core” option too.

 

Fidelizer - Enforce non-audio process to use only one core

 

It uses only one last core and that’s efficient core which is less powerful than physical core. No wonder why system is very slow after using Fidelizer Pro at Purist user level with this option. For now, please don’t check this option if you don’t want your system to be very slow and unstable.

 

I’ll release Fidelizer 8.11 to address the reported cases with efficient cores and resolve issues with Windows 11 soon. I’ll test a bit more and find out if there’s any other issues to be resolved for Windows 11. I recommend Windows 10 for better audio performance and reliability if possible.

Here’s another feedback today from a customer ordering Nimitra Classic + Nikola Classic + StreamHub streaming 16x sample rate through WiFi.

Thanks again for going above and beyond; my super high sample rates were a big challenge for you to overcome, and I appreciate all your efforts!

This has been the best customer support I’ve ever had in 40 years in the hobby, Keetakawee.

Best wishes and thanks again!
Evan

It was quite a challenge to optimize best possible sound quality with 16x sample rate through WiFi streaming and happy listening. 🙂

Hello,

I tried for a few days Fidelizer and I must say that I am very satisfied. What I didn’t understand is if, once you set up the software, this also works with the apps I use for streaming, Apple Music and Amazon Music in particular. Thank you for your support and congratulations for your software.

Best regards
Franco

I’m happy to hear that Fidelizer Pro also help improving streaming app as systemwide optimizations and happy listening. 🙂

Added iBasso DX200 Fidelizer Advanced ROM + Masterpiece Mod feedback from Alberto

 

iBasso AMP Module

 

Here’s another feedback today from iBasso DX200 user who visited Thailand recently. He shared me his feedback after receiving Fidelizer Advanced ROM + Masterpiece Mod as below.

In the main while thank you once again, and all my compliments for the result you have achieved on the DX200. When it is used as player for my car (the 85% of its use), your upgrade were by far more “pleasant and effective” than all the work I’ve done changing the whole set of speakers and the car audio amplification system.

I’m glad to hear that Fidelizer Advanced ROM + Masterpiece Mod can bring more pleasant and effective than his car audio upgrade. 🙂
