Microsoft Insider Preview Raises The Windows FLS limit

News that will possibly only affect a small number of users, but ultimately one that will make their composing life better. The FLS limit in Windows has become more and more apparent in recent years as computer performance has improved and the total number of plugins found within any given project has scaled too.

The FLS slot limit (Fiber Local Storage) has always been in place and places a limit on the total number of unique plugins that can run on a system. Multiple copies of the same plugin can share code and run efficently, so the previous limit of 128 plugs was percieved to be high enough for the average user.

The problem we’ve seen over the years is that some plugs don’t efficiently use their resources and can sometimes use up multiple slots per plugin. Some reports have shown that some software can eat up to 7 or 8 slots per unique plugin, so it should be apparent that for users working with large templates and intensive projects that the ceiling was ever looming.

Todays insiders announcement sees a new FLS limit being included in the download and should public testing prove positive we would expect to see this rolled out to everyone later in the year.

The new limits increase the headroom limit to well over 4000 slots, so this new limit should keep even the most demanding user going for a good few years to come!

FLS Slot Limit Increase

As PCs get more powerful, musicians have created increasingly complex projects with more tracks, more instruments, and deeper effects chains. As a result, some of those musicians were running up against a FLS (Fiber Local Storage) slot allocation ceiling that prevented them from loading into their DAWs (Digital Audio Workstations) as many unique plugins as they’d like. This build greatly raises that per-process FLS slot allocation ceiling, allowing loading potentially thousands of unique plugins. Beyond musicians, this change will positively impact any application that dynamically loads hundreds or thousands of unique DLLs that have statically-linked Visual C++ runtimes, or otherwise allocate FLS slots.


Windows 10 – Gaming The System

The next big Windows update will be towards the end of Q.1 this year and news about some of the impending features have been cropping up for a few months now.

Last nights confirmation of the forthcoming “Game Mode ” potentially offers up a surprising number of possible advantages for the audio system user.

Essentially the game mode is designed to cushion a running program against the calls and demands of the rest of the OS. The mode looks to restrict background tasks and process calls, claims are there that it can secure threads and cores and assign them exclusively to a running program. The hope is that it can intercept all the demands of Windows and allocate them a dedicated thread or two, in order to stop them causing problems for more important software running in the foreground. For the average audio software user this could smooth the user experience further we’re all hoping it will help to eak out even more performance out of Windows 10.

With the ability to assign the game mode to specific programs so that it may change and optimize the system settings on the fly whenever you open certain .exe’s, it sounds like this might be a boon for audio system users. Comments have also been made about further development and refinement of this mode going forward which is great to hear.

The announcement this week has obviously concerned itself with pushing the features from a gaming point of view, so news with audio software in mind is currently a bit sparse. The insiders update is due to go live today however and if your signed up to the program already might be of interest to check out.

Otherwise we can expect to see this roll out in the next major W10 update which will be content creators update in Spring.
