Godot3d performance

Schuster

Also don't forget Vulkan®..(planned for 3.2?)...it also adds some more performance :)

... given current ‘mid rangerd’ hardware can anyone share with me what I can expect?...

Looking at the results from Steam’s hardware survey may help narrow down what hardware you can expect players to have. It seems the current most popular GPU, according to the survey, is the Nvidia GTX 1060.

For reference, I’ve yet to run into any issues using my Nvidia 660 ti 2gb and 8gb of ram. I don’t remember my CPU but its nothing special, and is several years old.

(Not that I’d suggest developing with a 660 ti, since it is starting to show its age :smile: )

Is there a maximum world size?

I’m not sure on the maximum world size, but I’ve had to issues with some of the larger game levels/scenes I’ve made. I think it’s limited by the maximum float size, so it should be something similar to Unity3D’s limits. (Totally guessing though)

What are the maximum number of objects that can be handled

I have no idea. I have not had any issues with around 200 to 400 nodes (many of them either mesh instance nodes or static body nodes), so I imagine the limit is in the thousands if you are just using base nodes.

There is also several bunny mark projects on Github, which shows how many sprite nodes can be bouncing around screen at once.

Seen the tests :) I'm aware of FP percision on larger worlds :)...but you did attempt to get me some answers so, Thank You...clearly I will just have to test myself....as only I know what I am expecting to do with it anyway :)...thanks guys.

@Megalomaniak said: Well, current gen mid-tier is the 1080. I reckon it can do quite a lot however I don't have one of these myself so best I can do is point you to gpuinfo.org: https://opengl.gpuinfo.org/gl_generatereport.php?reportID=2409 and you can google for benchmarks.

I recently ordered a new PC build that will contain a GTX 1060 6gb, as I figured it will be enough for work in Godot (due to its intention to be a powerful yet lightweight solution, even in graphics). This will also be for the upcoming Blender 2.8 where the new viewport is also planned to not require a really beefy card (I mention 2.8 because it's inevitable that many Godot users will move to it).

As far as the 1080 being mid-range, right now they are at a very expensive price point for that moniker. People getting into Pascal late in the game should also keep in mind the upcoming Turing architecture from Nvidia and the planned new architecture from AMD that may make use of their Ryzen tech.

The Radeon Rx 460 is powerful enough to do advanced gaming. If you change the timer straps it is stronger than a GTX 750 TI. I know the GTX 750 TI is old stuff, but that is still a powerful card. And then the RX 480 and RX 580 cards can have their timing straps changed, making them more powerful, by 30%

But even with that, the RX 460 and RX 560 are strong cards by themself. They can handle blender, and high settings in games. They make good production cards at a lower price. Not as good as the Vega. Don't forget they have the 470 and 570 cards that can have their timer settings changed.

Yeah, I use a RX 470 8GB myself but technically for the current generation of cards it falls in the lower end of the mid-tier. Any game in development right now should still be targeting cards even lower than that however in terms of lowest graphical settings to be sure.

You guys are lucky to have RX 470 and GTX 750. I am still chugging along with a Radeon 6630M. I can run GRID 2 on medium at 60 fps, but the fps tutorial project in Godot is only 5 fps (surprisingly playable at 5 fps, though!)

You must deactivate costly features , for example SSAO in Godot is far from optimized, and get rid of GI probe if there is one. The FPS tutorial should run fine considering there is no texture and geometry is as simple as an old game like Unreal 1.

So me and the other people can have spec reference, what card would fit the mid tier? Would that be a GTX 460? I will visit the local search engine after posting.

I found a GPU statistics from Steam. They update it each month.

I think we are getting off topic, but I do not trust steam statistics....or any singular source for that matter...and no way is a GTX 1080 mid range :)

Yeah, no don't misunderstand gtx 1080 is the top of the mid tier. And that is in the context of speaking of current generation of cards. Basically its the variant of the mid-sized chips with no features cut out of it, where 1080ti and titan would be the full sized chips similar to the Tesla but with features cut off from them. Titan V and Tesla V100 wipe the floors with all these other cards, but then they are the next gen cards.

justinbarrett

but titan does not have a large enough user base to create even the slightest dip in any statistics....but...it's really not important ...and I am basing this entirely upon my own assumptions so.. :)
