![]() ![]() This proposed “dark matter” doesn’t produce light, but it also doesn’t block it, or we would be able to see it silhouetted against brighter stars and galaxies in the background (like we can see dust in the Milky Way). This hints at the presence of some kind of matter that affects stars and other bodies via gravity, but that can’t be observed directly. No one knows for sure what dark matter is, or even if it exists! But a number of different observations of our universe have revealed stars and galaxies moving under the gravitational influence of more mass than we can see. Left: Spiral galaxy with dark matter (pre-Update 23). If you’re looking for a more in-depth explanation, keep reading! Due to performance constraints, our simplified galaxy dynamics model can’t simulate these complex orbits, so we’ve decided to remove dark matter from our simulations for now. Here’s the TL DR explanation of why we removed dark matter in our new galaxy model:ĭark matter is a theoretical particle proposed to explain the unexpected motion of stars in galaxies. The dots were how we represented dark matter in the old galaxy model (pre-Update 23), but we’ve decided not to include dark matter in the new model, for a number of reasons. ![]() ![]() 7980XE running at 4.6GHz for example would be literally the fastest CPU you can run US2 on, it will demolish all Xeons except for Phi's or multi-socket systems (which I doubt US2 supports anyways.You may notice that our new galaxy model (added in Update 23, released on June 25, 2019) no longer includes those bright red dots. Just buy a computer with Ryzen 7 2700X, Ryzen 9 1950X, Intel Core i9-7900X or Intel Core i9-7980XE if you want some really good performance. And this won't likely change for a long long time, and with new features requiring even more processing power, there's no real need to even attempt to optimize towards perfection. The optimization for US2 as of now is very good. The task would take ages even for massive studios. And no one has time to waste on god tier optimization, especially for smaller studios. For example, even if US2 used up 100% of your CPUs power, meaning it is optimized very well, and was executing the code the best it could (with perfect code too.), after that, it'd be impossible to improve. To go beyond that, you'd need new algorithms developed to speed up processing and new APIs etc. The problem is that with all, including potato, computers, there's an absolute upper limit. I'm not set in stone (yet) but with my limited knowledge and lack of infinite knowledge and/or pretty good researching skills it's pretty likely I'm going to make a really big mistake at some point so if this, my first attempt at finding a good CPU for this or any PC is that mistake please tell me an direct me to something better, but I am on a budget here so I can't just build an infinitely amazing PC.Īlso, even with one of those guys, how could 4.7 GHz and 8 cores not be good?Īlso, due to the kind of long term usage of this thing I'd rather go with normal clock speed than overclocking.call me paranoid but I don't think overclocking something from really long time periods is good for said thing. There’s less latency because the cores can communicate more quickly, as they’re all on the same chip."Īt this point I'm probably going to have to use water cooling anyway.Īnd, I've been looking at a CPU that I would use two of that normally clocks at 4.7 GHz and can be overclocked to 5 GHz, and has 8 cores, so I'd say that at least based on those specs having two would be crazy good, even with a drop in performance because they're separate, but I am admittedly pretty new to this, so my choice of CPU could be totally wack for what I want to do, so for your opinion. There only needs to be a single CPU socket with a single CPU unit inserted into it—not four different CPU sockets with four different CPUs, each needing their own power, cooling, and other hardware. This helps dramatically improve performance while keeping the physical CPU unit small so it fits in a single socket. "A quad-core CPU has four central processing units, an octa-core CPU has eight central processing units, and so on. They are looking into ways to speed up US ² and may add GPU acceleration in the future, but they may find other ways that are faster.Īccording to the article in how to geek, a single CPU is more efficient than multi CPU's. Quote from: im4space on May 23, 2018, 06:48:08 AM I think that it was version 14 of Universe Sandbox ² that last supported GPU acceleration. ![]()
