Twibbit posted:Noita is almost all cpu based. Wonder if a port studio would be able to gpu accelerate some parts of the sim to make up for that I don't think that'd work too well - (afaik) GPUs are optimized for high volume low complexity very similar operations, whereas multifaceted simulations like noita's are more optimally performed by a CPU's more advanced logical suite

(Apologies if you're already familiar with this) generally the difficulties with GPU-based computation are a) getting data off of the GPU is expensive, and b) translating the data into a form the GPU can make effective use of is tricky. But Noita does have one big advantage: basically all of the effects they need to worry about are hyperlocal. In other words, a given pixel's state depends on the state of adjacent pixels, and (I think) nothing else. What that means is that in principle if you could get the data into a form the GPU can handle, then it could simulate thousands of pixels in parallel. And it's not too hard to imagine the GPU consuming, say, a texture that represents the world state using different colors for different kinds of solids/liquids/powders/gases. Then it outputs that texture to a second texture, which can be retrieved by the main game logic and also fed back into itself to simulate the next frame. So I don't think the concept is fundamentally flawed. The big gotcha that immediately comes to mind (and no doubt there's plenty of smaller gotchas as well) is conservation, i.e. not creating or destroying pixels. For example, say you have a 1-pixel-wide column of sand. Each pixel in the column could fall to the left or the right. Depending on how you write your sim, you might find that a given pixel might do both, replicating itself -- or do neither, and poof out of existence! I've no doubt the Noita devs had to wrestle with a lot of such bugs during development, and they'd have to start over, in a much more constrained environment, if they wanted it to run on a GPU.

Then it outputs that texture to a second texture, which can be retrieved by the main game logic and also fed back into itself to simulate the next frame. So I don't think the concept is fundamentally flawed. There is a rudimentary "falling sand" game that is 100% implemented in a shader (which, ironically, I can't find because Noita results are clogging up google), so putting the entire sim on the GPU is possible in technical terms, but it's super-hard in practical terms due to the enormity of the world. Noita also loses out on hyperlocality optimizations because of the large scale rigid body physics; they can't guarantee that interaction won't come from non-adjacent "pixels". This is mitigated by a grid-based threading system to cull / batch the interactions between grid units, but the whole world sim is being processed every frame so you'd have to have a huge amount of VRAM to contain the whole world in your texture (even though the physics sim isn't calculating it).

It already uses some LoD for the physics where certain simulations (like fluid dynamics) stop outside of a certain radius (usually outside of the visible screen area, unless you use mods), so that wouldn't be something new. The other thing to keep in mind is that the basic engine core might be highly optimized cpu c++ code, but a lot of the physics rules and mechanics are actually defined in gigantic lua scripts. So trying to get that stuff running on a CUDA kernel format would probably mean a complete rewrite (and also loss of mod-ability).

Man, I forgot about the rigidbodies. That's a good point, yeah. And to be clear, I wasn't trying to say it'd be easy. It'd be a ton of work no matter what.

Am I wasting my time trying to use a gamepad with this? The movement is easier for me to handle - as is usual for platformers - but aiming my spells is a load of old rear end compared to having a mouse.

Check out LetsSufferTogether on youtube/twitch for a dude who plays with controller and is pretty consistent at getting wins, does speedruns and has completed a 31 orb boss kill. It seems doable and he's pretty accurate at kicking stuff too. I've been having a lot of fun with the alchemy mods - I've got extra alchemy, random alchemy and the materials randomizer so every game is a different crazy mess. One game I'd get a kill, the gold would dissolve in the acid which the guys had instead of blood, and a poison cloud would poof out. But the midas formula kept naturally forming so getting gold was still possible. Another game I found a pool of naturally occuring lively concoction so I drank both the potions I had so I could scoop it up. But this caused some side effects... https://i.imgur.com/4eOGYbH.mp4 I've been granted unpredictable explosive farts, one of which knocked me into the lava (but thanks to randomized materials it's only worm attractant). The gas that comes out with each fart seems to cause berserk too. I thought this game had promise but one of my farts damaged the first Holy Mountain and even with berserk I couldn't handle Steve, he buried me in purple ash and I drowned.

I've turned into a total addict to this game, though it took a while to get over the initial difficulty/overwhelm hump This weird thing showed up in my first New Game this morning, right at the start  guess now I get to see what's under the lava lake! seed is 40974936 (e) lol i'm a liar, that's a lot of goddamn lava  maybe i can make it back from snowland with something more apropos. and a way to make it through the lake of blood left over...

Ah ok, I had never seen those things before. I think I still had over 100 hp but a split second after I started shooting them they turned me into a red stain. Almost thought I just flew too hard into that crevice and got physics'd.

I saw this suggested on Steam some time ago, added it to my wishlist, and haven't thought much about it since. Then I randomly saw this thread linked elsewhere and you guys easily convinced me to try it. loving amazing. I just wish I had more time to play with it.

Radical 90s Wizard posted:So I just put in a new cpu and a bunch of ram and welp, apparently I've been playing this in slow motion Yeah, after 160 hours played I finally tried the game on a proper cpu. I had to install cheatGUI and turn on a couple faster movement perks with my lenovo laptop now just to keep up the pace. I still experience slowdowns but at least I feel in control of my character with this poo poo computer.

Bizarre momentary rain cloud for no reason. Not a spell on any of my wands. Just before I had shot a chaotic transmutation that made that worm blood. Before that I had cast the summon wand, but it wasn't on any of the animated wand's spells either, and the wand was dead. Bonus:

Doesn't NG+ give everything ludicrously huge amounts of health? Which in turn means that they're full of blood (or slime, or acid, or bone dust, as appropriate). I could well believe that Breathless and Dissolve Powders would be necessary perks after you take More Hatred.
