A group of stalkers, for the first time, reaches the very heart of the Zone-the Chernobyl Nuclear Power Plant-and triggers a cataclysm on the brink of a catastrophe. An immense blast of anomalous energy transforms the Zone: the once reliable and relatively safe roads are no longer so, the landscape is wiped clean by outbursts of anomalies, and previously unknown areas appear on the Zone map. Stalkers and expeditions perish or end up isolated within the lost territories.

Old Story | The very Anarchy Cell Winter in Clear Sky Hybrid

Time has built up between the last update I shared about this project, many things have changed and many things will keep up changing.

I have been making changes on the software, and it is now fully open for new possibilities. Although this tool was initially designed for S.T.A.L.K.E.R., I made recent changes in its core libraries to make it both attractive and flexible. What does this mean? Well, let me show you:

- New GUI

S.T.A.L.K.E.R. Optimizer brand new GUI

The Optimizer will feature a brand new GUI, far more attractive than the previous interface. Each item will have its info box to let the user know what does each button do, things will be kept in the simplest way possible both to provide a harass-free experience and to keep the resources consumption to the minimum, while providing rich features and good-looking forms.

- Added flexibility

Optimizer console

While the main purpose of this tool was reducing the chances to get memory leaks and related CTDs with X-Ray Engine (S.T.A.L.K.E.R. games), I had another idea... a console to make this tool work for any process. With this full-flexible console, the tool will work for any process with three defined actions: DIRECT OPTIMIZATION, MONITORING, and TERMINATING. These integrated functions will allow the tool to optimize a process once, monitor a process and optimize it each interval of time, or force the termination of a process. BUT, as you may have noticed, this flexibility brings downsides. Many malicious users might use this tool to cause memory related malware like worms, or CPU hogging malware, and that is why I intend to keep the tool hard-coded.

What I mean is, while the tool will be able to assist ANY game in memory duties, I will NOT let the user access directly to the console to avoid issues. So if you want your favorite game in the next version's (not 1.0, but 2.0) list then just leave a comment with the name of the game or PM me about it and I will add it.

That said, I will include that from the next version (not 1.0, but 2.0) and on, the tool will be called "Memo Creeper" and will be fully flexible to support any process without issues.

List of new features -> S.T.A.L.K.E.R. Optimizer 1.0:

- Brand new interface.

- Internal code fully optimized

- Console based tasks for optimizing, monitoring or terminating processes

- Full integration with S.T.A.L.K.E.R. Engine (X-Ray) (via scripting)

Coming features -> Memo Creeper 2.0:

- Multi-purpose optimizer, with support for variety of games/engines

- Memory leaks recognition for internally listed games

- Automatic detection and termination of hanged games

- MAYBE a restricted version of the console to allow the user use it on other processes (with restricted I mean locked for certain processes and cut off from certain aspects)

- Detection of virtual memory addressed by process (and automatic optimization, if possible)

- Memory lock for unstable engines (good ol' X-Ray cited again, but also others like Source...if you played Vampires - The Masquerade Bloodlines you'll understand what I'm talking 'bout)

Don't forget to leave your opinion in the comments, and feel free to speak any suggestions out loud, Stalkers.

Regards, YeiZoneX @ CreepDev -> a group led by giant rabbits and brown unicorns with no horns.

So this thing is really essential? How about the patches? Everytime I try to install one it tells me my version is unknown. It's whatever is on torrents, US verison I guess.

From what I read it only has SOME of Complete in it. You can't use the spawn menus with just Arsenal Overhaul. I keep running into an issue where the game crashes on start when trying to use both mods, has something to do with xCore.dll

If it wasn't for missing locations from the first one it would be perfect.
