Thank you so much for your support! Have a great weekend!

A couple of weeks ago we introduced the Delve Stash Tab that allows you to store all Fossils and Resonators at one place in your stash. We've received a lot of requests from the community asking for a crafting slot in this Tab. Based on your feedback, we're adding two crafting slots in the upcoming 3.8.1d update which is scheduled for next week. Alongside this small QoL feature, the 3.8.1d patch includes further improvements and fixes. We'll tell you more about this patch soon.

Thank you for your feedback and continued support!

Last week we posted an update about our work on improving Path of Exile's recent client and serverside performance problems. While working on these areas, we identified a much larger problem and have deployed a hotfix for it today.

Due to a subtle change made in 3.8.0, a bug was introduced where certain effects on the client would spawn more particles on long frames than short frames. This meant that when the game client slowed down for any reason, it would start to take exponentially longer for each subsequent frame. A fix for this has been deployed today.

This particular issue causes small performance issues to turn into gigantic client freezes, which can be seen in popular reddit/forum posts since this bug was introduced with 3.8.0. Other work is still ongoing on fixing the small performance issues that were exacerbated by this.

In addition, we have found several areas of server performance that we can immediately improve, which will prevent the stuttering and slowdown that can occur when the game server instance is consuming far too much CPU. We expect to have these deployed today also.

We will continue to work on performance. Thanks for your patience.

The third week of the Blight League just started and we wanted to give you a small update about what we're working on at the moment. While we don't have a big patch scheduled for this week, we're still planning to fix some of the remaining issues by deploying client-side hotfixes.

The following crash fixes are ready and will be deployed as soon as possible:

• Fixed a client crash that could occur when using Shield Charge if you leveled the gem up while it was being used.
  
• Fixed a client crash that could occur when using Leap Slam with the Harlequin Leap Slam Effect on Predictive Networking Mode.
  
• Fixed an instance crash that could occur when using Mines.
  
• Fixed an instance crash that could occur in the Act 6 and Tower Map Brutus and Shavronne encounters.

The common crash with Vorici Betrayal encounters is still being worked on, as well as the cases when the Blight portals spawn too close to the Ichor Pump.

Last Friday we talked about the current performance situation in Blight. The team has been actively investigating the high priority issues we listed in that news article. We'll give you more details about the changes we're planning to make in order to improve the performance by the end of this week.

Game performance and stability have been hot topics in the community recently, so we wanted to give an update about our understanding of the current status of several of the important issues, and to reassure you that we are working on them. For many of the issues, we haven't yet identified their causes, and we'll update with more information as soon as we have. We felt it was important to post this before the weekend so that you know that the concern has been heard.

Blighted Map Instance Server Performance
When we talk about instance server performance, we're referring to the performance of the game server software that is running on one of our server machines. Normally we can fit dozens of instances per CPU core, and they take a fraction of a millisecond to process your actions for the frame. Under extreme gameplay circumstances though, the instance server can slow down due to the calculations taking a full CPU core more than 33ms (the serverside frame time).

In Blight, there are a lot of monsters and they have a lot of life. What normally happens when you engage a pack of monsters is that your attacks quickly cull out the weak ones, leaving just a few strong targets. In Blight, however, the weak ones last for much longer. As you know, Path of Exile has a very complicated stat system with tens of thousands of different values that your character can have. Many of these are used in combat calculations and dozens of small buffs, debuffs and ailments are applied to monsters as you attack them. The more monsters there are, and the longer they survive your attacks for, the longer these calculations take. Blight combat is an order of magnitude more strenuous on our servers than regular map content.

Once we knew that we had serverside performance issues with Blighted Maps, we wanted to check whether we could improve this issue by adding more servers. We observed that on physical game servers with different numbers of game instances, the number of dropped frames per instance was not higher on more heavily-loaded servers. This showed that the problem is related to specific instances utilising an entire CPU core for more than 33ms, rather than the server itself having too many instances on it. Throwing more money/servers at the problem would not solve it.

We are working on this problem and trying to find a solution that will reduce the calculation complexity without compromising gameplay.

Minion Performance
We believe that the popularity of minion builds with 3.8.0 have caused a lot of the performance problems that players are encountering.

Minions are monsters, so all of the problems mentioned above apply to them. They tend to last a long time and there are a lot of them on the screen, all of which are getting all the various buffs and graphical effects that would normally apply to players.

Alongside the release of legion, we made many changes to how melee combat works in Path of Exile. Our changes intended to tighten up attack distances and to get stuff to feel right had the side effect of slowing down pathfinding and causing a few other small performance regressions. We didn't notice at the time how much extra cost these added to minions.

With the 3.8.0 release making minion builds very popular, all of these performance problems have become a large issue for anyone playing minions, or in a party with minions.

These issues are a high priority for us.

Graphics Driver Crashes
While playing certain content (e.g., Betrayal missions), some users experience a graphics driver crash where the screen goes black for a while, and then comes back with a Path of Exile "Map" error. Recent versions of the Nvidia driver including the most recent, 436.30, have this issue. We can't reproduce the problem on Nvidia driver version 419.17. We don't yet know what Path of Exile is doing to cause the crash, but the graphics driver should never crash regardless of what the game does. We have contacted Nvidia to bring it to their attention.

(A few AMD users have reported similar problems but we haven't been able to reproduce this and it doesn't appear to be on the same scale).

Instance Crashes
Instance crashes are when the game instance server crashes while you're playing, disconnecting you back to the login screen. Since Blight's release, we have deployed many hotfixes that address various instance crashes and the number of crashes is dropping by the day. Today we have deployed a hotfix that resolves more than half of the remaining instance crashes. We are still working on the remaining ones, focusing attention on the most-frequent first.

Client Memory Usage
We have noticed unusually high memory usage, likely due to loading too many game assets. We believe this may be causing performance issues and we are investigating.

Engine vs Gameplay Performance
Recently there have been a lot of community posts criticising Path of Exile's engine for being slow or not optimised enough. We have spent several years improving the engine and have deployed these updates as soon as they have become ready. Path of Exile's engine is currently modern, lean and fast. But yet, in many situations, the game does not perform well at all.

Almost all of the performance problems that Path of Exile suffers from are related to gameplay systems and decisions we have made there. For the reasons described above, Blight is a league with performance problems. We made a conscious decision to try this type of league, and it's entirely appropriate to blame us and this decision for the poor performance that you may encounter while playing this content. We weren't expecting it to be this bad, and are working on fixing it.

No matter what engine we are using, Path of Exile would be slow in its current state due to the gameplay decisions we have made: calculating too many things on the server and rendering too many things on the client.

It may seem arbitrary and defensive for us to point out the difference between the engine and the gameplay systems, but the reason is that the engine is going to be part of Path of Exile forever, but the gameplay code comes and goes as things are added and removed. We don't want leagues to have performance issues, and this informs the decisions we make about future content development.

We're sorry that this post doesn't contain more definitive steps about exactly how and when we will solve these issues, but we wanted to communicate the status of these issues before the weekend. We are treating them as high priorities and are hoping to find and deliver solutions to many of them next week.
