Week Fifty Nine is here, and we’ve focused this update on multiple dedicated server and core game bugs and improvements that have been reported and ticketed over the New Year period.

The Dedicated Server search functionality has received an overhaul, with new ways to tag and sort your favourite servers, and faster load times with more details to make scanning results simpler and more efficient.

A large number of core game bugs were reported to us by our player base, and we’ve addressed the majority of them this week. Check out the long list below, with more in the patch notes.

Finally, we’ve gone into depth about our strategy for dealing with ongoing performance issues and the five key areas that build our approach.

Dedicated Server Fixes

We’re improving the Dedicated Server search results functionality this week, taking on considerable community feedback and data to improve the UX for players.

• Added the ability to search for servers via IP address, with its own ‘Direct Connect’ tab
• Disabled the engine LAN search option for Steam's LAN searching instead due to the game crashing while switching search types
• ‘Game Version’ on Dedicated Server results that are out of date are now easier to read
• Added ‘Friend' and 'History’ tabs to the server browser - Joining a server will now add it to the History tab
• Increased max server results to 10,000
• Servers will now show up as they appear without the need to refresh the list or restart the game
• Servers can be marked as ‘favourites’ and will show up in a ‘favourites’ tab
• Added ability to connect via ‘Lan’ for local connections, with its own ‘Lan’ tab in the table
• Server tabs are now ordered ‘Internet - Favourites - History - Lan - Friends - Direct Connect’

Core Game Fixes

Alongside our Dedicated Server search results improvements, we’re addressing a range of core game issues that were raised over the Christmas period.

• Fixed an issue where clients were unable to place or rotate wall signs
• Fixed an issue where clients using the glassworking bench, were not being correctly displayed the ‘yellow’ border around an item when water was added, signally the item would be ‘reinforced’
• Fixed 'Out-of-bounds' check not occurring when the player was seated on mount
• Investigated and Fixed Issues with Healing Module not always applying the Aura
• Fixed an issue where enzymes geysers were spawning each time you started a session making it seem like their count was resetting
• Fixed an issue where killing animals with your mount could fail due to a bug
• Fixed an issue where the UI was allowing players to deploy items in the space station
• Fixed an issue where the fridge/icebox were displaying incorrect spoilage timers for clients and causing issues with spoilage
• Fixed a bug that was causing sort options to not work on containers
• Fixed an issue where modifiers would sometimes fail to clear in the UI when timed out
• Fixed a bug where players would unexpectedly lose an attachment when removing multiple from an item
• Fixed an issue where people could lose items in space by ‘control-clicking’ in some circumstances
• Fixed an issue where the grace period was not being applied while seated in the dropship for some players
• Fixed an issue where item spoil timers wouldn't take into account the proper multiplier stats when combining stacks or removing from stacks. ‘Sturdy Stalks’ talent, for example, should now work as expected.
• Damage Types and Colors have been revamped, with new damage types being added for future content. Felling damage is now displayed when cutting down trees instead of melee damage.

Performance

For new players and old, performance is a frequent topic of conversation, and we’re aware of how important it is to you all. At this time, we have half of the Icarus Tech Team dedicated to this task.

While we are doing our best to get these fixes to you as fast as we can, changes related to performance require thorough investigation and careful consideration before any decisions are made. Rushing headfirst in often causes more damage than good.

We are currently focusing our efforts on five main areas:

Engine Performance

Many of the systems we use in Icarus are provided to us as part of Unreal Engine. Our philosophy has always been not to fight the engine, but at times we have found it necessary to tweak the way some of the systems work in order to achieve some of our goals.

Game Systems

In many of our weekly updates, we do our best to bring you new gameplay features that add dozens of hours to your gameplay experience in Icarus. At the same time, we are doing our best to continue to profile the game, in order to minimize the number of operations that need to occur on each frame.

Memory

Loading gameplay features into memory has a knock-on effect - the loading of one object can trigger a long chain of other objects to load alongside it. In order to prevent this chain reaction from using up too much memory, one of our focuses is to scrutinize the dependencies that form between objects and remove them wherever we can.

Stutters & Garbage Collection

One of the many features of Unreal Engine is automatic garbage collection. Convenient as it is, it can sometimes result in stutters during gameplay when large amounts of memory are reclaimed at once. We are investigating different ways to work with the engine to better minimize the impact of this step.

Connection

There is no “silver bullet” when it comes to optimizing networking - it mainly comes down to the continued efforts to profile the multiplayer experience, reduce the size of the network packets we send, and reduce the number of packets we need to send each frame.


As we continue forward we will continue to make small improvements every week to address all the issues mentioned above. These fixes and optimizations are cumulative, with the improvements in performance in the last 12 months a reflection of this ‘piece by piece’ approach.
