OpenMW is an open-source open-world RPG game engine that supports playing Morrowind. Main repo and issue tracker can be found here: https://gitlab.com/OpenMW/openmw/Project mention: Low FPS on Steam Deck | /r/OpenMW | 2023-11-04
I downloaded the build via openmw-0.48.0-Linux-64Bit.tar.gz, it runs very well, but whenever I add the game as a shortcut to steam, the performance fumbles, I get around 25-30 fps at best, and I tried to experiment a bit and search more on the internet for a solution before posting in here, but nothing have helped as of yet. If there's someone who worked it out, please share it with us.
Cocos simplifies game creation and distribution with Cocos Creator, a free, open-source, cross-platform game engine. Empowering millions of developers to create high-performance, engaging 2D/3D games and instant web entertainment.
Space exploration, trading, and combat game.Project mention: Naev – open-source game about space exploration, trade and combat | news.ycombinator.com | 2023-11-25
Sounds very similar to Endless Sky - another open source game drawing on the old Escape Velocity games. I really enjoyed both Endless Sky and the Escape Velocity games, so I'll have to check out Naev at some point!
Open-source, cross-platform, C++ game engine for creating 2D/3D games.Project mention: Alternative Game Engines for Marooned Unity Developers | /r/gamedev | 2023-09-22
Gameplay: Another promising MIT licensed engine for both 2D and 3D. Doesn't seem like there is much in the way of learning material though.

ossia score, an interactive sequencer for the intermedia artsProject mention: Show HN: New visual language for teaching kids to code | news.ycombinator.com | 2023-11-21
> I feel like visual programming gets a bad rap because of things like this. As an electronic engineer that used to love LabView and life long user of NI Reaktor and Max/MSP, those tools are fantastic if you don’t approach them with an imperative programming mindset.
aha, in the long run I ended up making https://ossia.io which is as VPL as it can get. Yet it still embeds a LOT of textual languages.
A privacy-friendly Document Scanner appProject mention: Can someone recommend a FOSS document scanning app for Android? | /r/foss | 2023-02-01
Here's the GitHub for the project, and here it is on Google Play.
Insight Toolkit (ITK) -- Official Repository. ITK builds on a proven, spatially-oriented architecture for processing, segmentation, and registration of scientific images in two, three, or more dimensions.Project mention: Create Elegant C++ Spatial Processing Pipelines in WebAssembly | dev.to | 2023-02-10
The itkImage.h header is ITK's standard n-dimensional image data structure.
The official repository for the gem5 computer-system architecture simulator.Project mention: Hot Chips 2023: Arm’s Neoverse V2 | news.ycombinator.com | 2023-09-12
The idea is to write a C++ model that that produces cycle accurate outputs of the branch predictor, core pipeline, queues, memory latency, cache hierarchy, prefetch behaviour, etc. Transistor level accuracy isn't needed as long as the resulting cycle timings are identical or near identical. The improvement in workload runtime compared to a Verilog simulation is precisely because they aren't trying to model every transistor, but just the important parameters which effect performance.
Let's take a simple example: Instead of modeling a 64-bit adder in all its gory transistor level detail, you can just have the model return the correct data after 1 "cycle" or whatever your ALU latency is. As long as that cycle latency is the same as the real hardware, you'll get an accurate performance number.
What's particularly useful about these models is they enable much easier and faster state space exploration to see how a circuit would perform, well before going ahead with the Verilog implementation, which relatively speaking can take circuit designers ages. "How much faster would my CPU be if it had a 20% larger register file" can be answered in a day or two before getting a circuit designer to go try and implement such a thing.
If you want an open source example, take a look at the gem5 project (https://www.gem5.org). It's not quite as sophisticated as the proprietary models used in industry, but it's a used widely in academia and open source hardware design and is a great place to start.
C++ open source 3D game engine
An FPS/RTS hybrid game powered by the Daemon engine (a combination of ioq3 and XreaL)Project mention: Murnatan not running | /r/linux_gaming | 2023-04-08
I would recommend Unvanquished instead. It's basically the same game but FOSS, much more polished, and there's a small but active community. Servers are often empty, but people will eventually come if you join one and you can play against bots in the meantime.
Cross Platform Professional Procedural Terrain Generation & Texturing ToolProject mention: Procedural GPU based High Resolution(8K) Realtime Procedural Terrain Generation (Source in comments) | /r/proceduralgeneration | 2023-02-28
Sorry, but i have temporarily removed erosion system from the current working version for cleaning up the generator system and the last video I have of erosion in action are from a year ago. As for the node editor tough https://www.youtube.com/watch?v=Ej80EWo9DH4&t=4s&ab_channel=JaysmitoMukherjee is somewhat relevant but a lot has been added/improved. I will make more videos as things start getting together in this version. As for erosion in action I do have a image https://github.com/Jaysmito101/TerraForge3D/blob/gen2/Screenshots/Showcase/Volcano.png you can see slight effects of erosion. Also I will be sure to post the showcase for erosion/other features here as they are ready.
