We’re standing up the PTR again and asking for your help to test some big changes coming down the pipe. Here’s the TLDR: we’re changing how graphics work in SCR. Please test on the PTR to make sure your video card doesn’t run into any problems. https://us.forums.blizzard.com/en/starcraft/t/return-of-the-ptr/1434 | ||

And they're pushing it because deadline is over because of their incomptency and now they're obliged and forced to do it. Blah blah blah. Don't care. If you break it fully we're all going back to 1.16.1. CEF is used for the majority of UIs in the game (all the menu stuff, bnet, and also for the ingame observer UI). It's an embedded version of Chrome, so it is indeed pretty bad for them to be shipping significantly outdated versions of it, given how many potential known security vulnerabilities it can contain. The fact that it's taken them this long to fix the "CEF spawns 5+ memory-hungry processes for every single piece of UI on the screen" problem is pretty perplexing though. What is even more perplexing is that they've seemingly spent the last few months writing a brand new rendering backend for Windows users (who was asking for that or even complaining about performance outside of the CEF bug and other things that have nothing to do with the rendering technology?), and even more perplexing is that they wrote one for macOS too. They probably spent more hours working on that than they have mac users. On May 16 2020 05:00 blabber wrote: from the message it seems like they need to do it for compliance reasons. I'm guessing the older technologies are no longer supported. hopefully we can do our part and help test the changes and make sure it works so it goes smoothly. The "compliance reasons" part is specifically about CEF (the thing they had to roll back before), it does not apply to the new rendering stack. I don't know why they combined those two pieces so closely (or maybe the community person just didn't understand what the devs told them). | ||

DirectX isn't available there and OpenGL is being deprecated. They needed to rewrite the backend in Metal. | ||

As for the render backend: Why not go for vulkan if you're gonna rewrite it in metal anyway? Available on any OS so you can throw directX out of the window as well. Either way I'd rather have them invest their time into fixing bugs + improving their anti-cheat tbh. Or hell atleast bring OG graphics up to par with a 1.16 client. Though I guess if you are shipping with an outdated version and using a depreciated API like openGL, you really have no choice. | ||

Though I guess if you are shipping with an outdated version and using a depreciated API like openGL, you really have no choice. I very much imagine that all of the cards that need the DX9 renderer currently also don't support Vulkan (or have showstopping bugs with it). I don't get how moving to DX11/DX12 really removes the need for a DX9 renderer though, given that there are a number of cards they claim to support that are DX10.1 or below. Perhaps they're just stealthily trying to cut support for those cards again and going to see how many people complain? As far as the original graphics go, they mostly look terrible at this point because they decided to compress all of them like they did with HD graphics. The savings for SD-sized sprites end up being quite minimal (especially compared to how much memory they use up through other bad decisions), but the loss in fidelity is quite immense. Fortunately they still ship the original sprites in the game data (likely because SCMDraft doesn't support the compressed versions), so someone could feasibly write a renderer that used them and actually looked decent given enough time. I definitely don't think there's any reason a browser-based UI *has* to be non-performant, and a number of games do it well. SCR's, however, has a lot of really questionable decisions. Every little piece of their UI is loaded up in an isolated frame, every page has a separate HTML file (that all follow the exact same, very simple template), every piece has its own isolated javascript file that has been compiled for very, very old browsers and thus includes a ton of code to implement stuff the game's browser obviously supports. Every javascript file bundles all of its own dependencies (the vast majority of which are common between every piece, but have to be parsed and executed without any shared caching because of this setup). The pieces communicate between each other and the game using a WebSocket, but the protocol used is often incredibly chatty and wasteful. For instance, the Observer UI sends an update for every mineral count change containing the player's name and all of their resource state (that is, if a player spends 50 minerals from 100 minerals, an update is sent not just for 100 minerals and then 50 minerals, but every step of the animation along the way: 100 -> 97 -> 94 -> 91 -> ... -> 50). Each of those state updates then re-renders the entire UI, and mostly happens far faster than the game can actually render a frame in general. Yeah, you can get away with these kind of things when all the communication is happening locally, but god that has to be eating up so many resources and making things perform so much worse. But instead of fixing this kind of low hanging fruit, they're rewriting the whole rendering backend? Truly baffling. | ||

Do they not play the game? lol >_< | ||

Thing is, switching to a new rendering backend isn't going to change that at all. It may even make it worse, given that they seem to devote a lot less energy to actually ensuring things work before they push them out to everyone at this point. All the non-game UIs (and the in-game observer UI) are handled via CEF. CEF is an embeddable version of Chromium, which renders via Skia. In a "real" browser, or when CEF is managing an actual window, Skia supports hardware acceleration (e.g. using DirectX or OpenGL to render graphics with your graphics card, rather than software implementations), but CEF does not support hardware acceleration when rendering in "offscreen mode", which is how SC:R uses it. Thus, all CEF is doing here is rendering out to an image via your CPU, telling SC:R what pixels have changed, and letting SC:R deal with putting those pixels on the screen. This isn't a hard operation for a graphics card to do, and there's really nothing complex about the code they'd have to do it, regardless of graphics API. There's no real room for further optimization by choosing a different rendering API, as the bottleneck is not there. Very likely, memory problems and bugs you are seeing are due to things that they aren't working on at all here: wasteful allocations and initialization of things that aren't needed, not following or paying attention to best practices when it comes to developing web UIs, inefficient communication between UIs, spinning up far more expensive background processes than is actually needed, etc. This is like painting your car a different color because you see it's been getting bad fuel efficiency. | ||

You can compare the versions of libcef.dll in the PTR and non-PTR versions and see they are they same: ![[image loading]](https://i.imgur.com/2qRpzz3.png) Thus, this update still hasn't been rolled forward. I had never actually gone and looked up what Chrome version that corresponds to, but apparently it's from April 2015, which... oof. | ||

The patch doesn't seem to contain many other changes from further inspection. The UI scripts look to be the same other than a few things renamed here and there, nothing functionally different as far as I can see. | ||

I imagine that's because the display is 60 Hz -- however, and I'm not sure if this is placebo or not, but now both modes feel (equally) a little choppy, whereas SD at 200 FPS seemed to be smoother previously (and HD unplayable). SD graphics is still looking terrible, so no improvements there. | ||

Turning it off or on made no difference. I found, however, that going to windowed, and then back to windowed-fullscreen made the FPS go up... It reached a 100 in HD and 150 in SD! Damn, lol :D Should probably test on windows 10, but there's not enough space on my bootcamp partition to install PTR I think... edit: After resizing partitions and testing on Windows 10, I can say that it's a similar experience under Windows 10 as well. Except the window hack doesn't work here, and I get a capped 60 FPS both in HD and SD, whereas with the regular version I get a 100 FPS in HD and 150 in SD. If I go to windowed mode, I get 200 and 300 FPS respectively. I'll post on the official forum as well and hope that by the time they roll this update out for real it'll support intel integrated graphics properly as well... | ||
