If you do not want to keep Process Lasso, there is an uninstall.exe in the Process Lasso program folder that you can access either via a command prompt or, better still, by running Q-Dir (freeware) which gives you a File Explorer type window in core mode (and only runs when you open it). If you would like a few tips in setting up Process Lasso Server after installation, PM me. Note: you will need to do a full reset of drivers and services with the Service Tool (ST -r) to install Process Lasso cleanly. Since the trial is free, and it does not make permanent changes to your system, it is worth giving it a go. There is a free trial version of Process Lasso Server version, and the only way you will know whether Process Lasso gives you an improvement is to try it. The bottom line is that running all three is not redundant. In this respect, there is some complementary (but not identical or antagonistic) overlap between Fidelizer and Process Lasso with respect to core usage. Unlike AO and Fidelizer, Process Lasso does not seek to change the number of services, processes, etc running, but rather the way processes are used (see the PL info on their site for a more detailed explanation). Certainly, there is no negative impact in GUI mode in my system. If there was a negative impact of running Process Lasso on sound quality in core mode, I suspect that someone would have mentioned it by now. I use AO, Fidelizer and Process Lasso with WS2016 in GUI mode in a dual PC system, but there are other forum participants using all three in core mode. I use JPlay Mini for playback on Control-PC so I do not need networking services at all. I am wondering if FP and AO already address what Process Lasso does, and if having more processes running would actually make things sound worse? Should I also use Process Lasso?ĭoes anybody have experience using ALL three of these together? I am using Audiophile Optimizer and Fidelizer Pro. Process Lasso v10.4.0.I have a JPLay Dual PC setup and am running Windows Server 2016 Core, no GUI, on BOTH the Control PC and Audio PC. Users can still select this option in the installer sections, or access it later via the menu item ‘ Options / General / Configure Startup…’. The startup configuration dialogs had became unnecessary since almost all users went with defaults after the switch to Governor-as-a-Service a few major versions ago. Product installation was also streamlined in this release. E-cores are demarcated by an ‘E’ appendage to the CPU indices in applicable dialogs and menus.Īlder Lake Efficiency (E) Cores Streamlined Install This change required some adaptations of Process Lasso, and that is now complete. The P-cores are Hyper-Threaded, the E-cores are not. Intel 12 th Gen (Alder Lake) CPUs diverged from traditional PC CPU chip topology with their P+E hybrid design, offering a combination of Performance (P) and Efficiency (E) cores. Persistent (Sticky) CPU Sets are fully supported by Process Lasso. Many users will find CPU Sets an ideal method to disable E-cores for select applications.įor systems with more than 64 logical CPU cores, CPU Sets are also processor group aware, and a process’s CPU Sets may span multiple processor groups. On Intel 12 th Gen CPUs (Alder Lake), CPU Sets can be used to signal the OS to only utilize Performance (P) or Efficient (E) cores, or some mix of each, for a process. In these cases, CPU Sets are a viable alternative since they are less likely to cause complications. Some apps and games are sensitive to CPU Affinity changes. For hard limits on CPU consumption, traditional CPU Affinities should be used. Therefore, for performance tuning, CPU Sets are usually preferred. In contrast, a CPU Affinity can not be violated, so the process’s compute would be limited. If a process with a CPU Sets rule needs more CPU(s) to handle its thread load, the OS can schedule onto CPUs outside the assigned Sets. This may be necessary when the thread load exceeds the number of cores in the Set, or for power management reasons.ĬPU Sets give the OS thread scheduler more flexibility than CPU Affinities do. The OS will try to abide by a CPU Set, but has discretion to schedule outside the Set. Instead of a hard contract, they are a suggestion of preferred CPU cores. CPU Sets, a native Windows feature, are a ‘softer’ form of CPU Affinities.
