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.

Audirvana Partner

 

Today we have very exciting news to share with Fidelizer fans. Fidelizer is now partnered with Audirvana company. Through past years we’ve been setting up Audirvana software to work with Nimitra as both uPNP endpoint device and server to run Audirvana software.

Audirvana has been supportive with Fidelizer software for many years. After they launched “plays with Audirvana” partner program, we immediately reached out to Audirvana and conducted extensive tests with them to make sure everything will work smoothly with Nimitra.

Audirvana X FIdelizer partner program went smoothly and now Nimitra customers can purchase Fidelizer Nimitra server with Audirvana 3 months free trial program. Customers who purchased Nimitra before can request for setting up Audirvana with 3 months free trial too. 🙂
