Unreal Engine 3 works on Linux via Stage3D

[fernandoc1]

I had some issues with the demo.

We could join some problems and send them to Google, so they could properly fix them as fast as possible.

Here is what happens here:


My hardware is (info from chrome://gpu/):
GPU0 VENDOR = 0x10de [NVIDIA Corporation], DEVICE= 0x0401 [GeForce 8600GT]
Driver vendor NVIDIA
Driver version 295.40
Pixel shader version 3.30
Vertex shader version 3.30
GL version 3.3
GL_VENDOR NVIDIA Corporation
GL_RENDERER GeForce 8600 GT/PCIe/SSE2
GL_VERSION 3.3.0 NVIDIA 295.40

I've recently seen a video on YouTube entitled Web Browsers in Linux Suck. The guy was comparing the performance of web browsers in Windows to Ubuntu with tests from Internet Explorer 10 Test Drive.

The FishBowl test on Chrome Beta works much better if the "--ignore-gpu-blacklist" flag is set but I still get only about 60fps (with 10 and 25 fishes) and it's not smooth at all.

fernandoc1 you have to start the browser from terminal with this command:

google-chrome --ignore-gpu-blacklist

When comparing Stage3D and WebGL in the cube demo I get half more frames per second with WebGL.

Rendering 1000 cubes

Stage3D 15fps (openGL rendering)
WebGL 30fps

Web Browsers in Linux Suck? No, Microsoft benchmark sucks. Check http://people.mozilla.org/~jmuizelaa...fishie-gl.html

That's what I thought when viewing the video. Why would anybody look at Microsoft benchmarks desinged for IE.

With Mozilla demo running on Chrome Beta I get 35fps with 1000 fishes and still it's much smoother than the Microsoft benchmark with 10 or 25 fishes.

I've found some good demos of Stage3D. They are created with Minko a 3D framework for the web. Aerys company behind that technology already works on Minko 2 which supposedly will bring big performance improvements. The game they developed with it runs much better than Epic Citadel but it's also even less impressive graphically The Mirage.

Should I even attempt to watch it?

Well, I did. Here are the important parts for people who don't want to spend that time:

1. Maybe I didn't hear it but I think he didn't say anything at all about his test setup. in one comments he says he has intel HD 3000.
2. Firefox has no acceleration whatsoever in linux? I don't think so.
3. Does the particle acceleration test even work correctly? In google chrome 23 I get steady 60 FPS with vblank_mode=0 and gpu vsync deactivated in chrome flags. DrawTime massively depends on the browser windows size. 4 ms for ~1024x768, 2-3 times as much when the browser is maximized on 1920x1080.
On firefox nightly I get 3-4 FPS no matter what. That seems to be a particularily bad example.
4. With chrome 23 I have 60 FPS with 250 fish in the fishbowl and 50 FPS with 500. Water looks fine.
Firefox nightly: as in the video

My chrome on linux acceleration with the (still not very efficient) open source radeon driver is much better than his windows acceleration? Therefore: "Web Browsers in Linux Suck."

*loading a website from cache* "it's not my web connection!"
*... disabled = true* "As you can see I did turn it on"
"I've never actually got the fishbowl test to load under linux anyway so it's inferior" WAT

*It comes up so fast it's probably still from cache* "There you have it, linux is inerior when it comes to web browsers"

*obnoxious condescending laughing. Repeatedly*
*more obnoxious laughing while calling the browsers on linux "garbage" and repeating that they fall short*

comment from video author: "YouTube videos if i go full screen the video is choppy in Linux and smooth in windows on the same hardware and browser."

If anything was "pathetic" than it was his presentation.

This because you didn't set "--ignore-gpu-blacklist" like the OP said. Otherwise it looks the same
on my hardware. Not a bug.

Ok, last experiment. I installed FGLRX and... Epic Citadel is still slow. ~25 fps @ ~1280x720.

Mmm, no luck even launching chromium with: chromium-browser --ignore-gpu-blacklist

It does not work that way with newer chrome versions, but you can use a much simpler way via:

chrome://flags

Ok, and wich flags I should change?

Thanks in advance!
