Empty); The mouse action being slow as you've described it is likely just a lower frame CSS transitions that previously were smooth now they run slower and feels choppy, the game its running at more than 2000FPS so isn't a engine rendering issue (at first), i dont know if i've missed something in the process of upgrading from 33 to 41 that could make the rendering to be slower on offscreen, it also gives the feeling to be out of sync, for example, i It can get bit complex with those settings, or not, for me at Italy turning reflections up actually decreases GPU usage as there comes CPU load too, that is without vsync and fps limiter, it then depends from your CPU if it is enough to feed GPU so that GPU stays at limit all the time, if not there is then more chance for GPU to render stuff that does not rely on CPU and no issue I am currently working on a C++ application that uses CEF to render a webpage (UI) over some OpenGL content. 13+g481a82a+chromium-87. Our implementation uses a custom WebContentsView and RenderWidgetHostView class to prevent the rendering This option is recommended for use in combination with the Cef. 9+gc7345f2. g0451528 32bit on windows 10, still seeing the same problem. 1+gb2b49f1+chromium-81.

DoMessageLoopWork). 2357. By default CefSharp uses setting. So, my question is, whether it is possible to use GPU for off-screen rendering in order to make rendering process faster. IME support in off-screen rendering mode #290. I use Offscreen CefSharp to solve my task. Offscreen rendering lets you obtain the content of a BrowserWindow in a bitmap or a shared GPU texture, so it can be rendered anywhere, for example, on texture in a 3D scene. 6; We're trying to implement an offscreen rendering mechanism for Electron based on the approach CEF uses, but ran into some performance issues, which are probably related to Electron. Also, CEF hasn't used Google Code for some time, you should really be looking at the Bitbucket issues if you want more up-to-date info. Tested over: 78. asked Apr 30, CEF will use software rendering if your GPU or drivers are flaky and have been blacklisted by Chromium. cefclient --multi-threaded-message-loop --off-screen-rendering-enabled --lang=en-US --disable-surfaces --disable-gpu --disable-gpu-compositing --disable-gpu-shader-disk-cache disable-gpu-shader-disk-cache should disappear if a --cache-path is set, unlikely this is an issue, couldn't hurt to test I am running cefsimple in offscreen rendering mode in macos (ventura, arm64) and with this I am getting pixel buffer in OnPaint(). 113 / Chromium 81. 3626 to latest version, it seems the webgl is lost for my testing on Fedora 31 while it works fine on Windows10 Switches Code: Select all--no-sandbox --disable-gpu-vsync --disable-gpu-compositing --off-screen-rendering-enabled Log: Code: Select all I ran the cefclient sample with the command cefclient.

Disable using settings. To implement off-screen rendering with CEF3 and the Content API we will need to provide our own WebContentsView and RenderWidgetHostView implementations via For best off-screen rendering performance (CPU usage, etc) with 2272 branch or trunk use the '--enable-begin-frame-scheduling' command-line flag. I have to pass this pixel buffer to another app (process) so I have created IOSurface and copied pixel buffer into it. I've tested with two different systems, one Windows 7 with Nvidia GPU, the other Windows 10 with ATI GPU. I'm trying to make a headless (docker) build of an application (casparcg-server) that uses CEF. Actually the gpu-process looks like no action at all, consuming no cpu resource. I'm using version cef_binary_100. We're using off-screen rendering and an implementation that calls CefDoMessageLoopWork() within our own loop. 4472.

We would like the renderer process for the offscreen browsers to have different options than the main renderer for the windowed browser and I'm having trouble figuring out The built-in shaders support transparency (with automatic depth sorting) and anti-aliased wireframe rendering based on an improved version of Single-pass Wireframe Rendering that does not need a geometry shader. "Unstable" here means that the GPU process crashes basically on every buffer swap. 141 73. ; Is &buffer a LPDIRECT3DTEXTURE9, aka buffer of DIRECT3DTEXTURE9 type? Read the rendering code ImGui_ImplDX9_RenderDrawLists to understand what is happening. But we now need it to work in a openGL 3. 1 changed between Basically I want to be able to render a video animation using the offscreen rendering API, specifically the "3D View into Texture image sequence) using the GPU Off-Screen Render API, at any given resolution (even 1920 / 1080) in Blender 2. google. Is there a way to retrieve directly the id of the texture used on the GPU for offscreen rendering, instead of having to copy a buffer to another texture like I do ?
