This primarily involves situations where the context is being switched amongst multiple threads from the same application.
Open GL 4.5 is being released today as a final specification, and based on prior experience we expect to start seeing desktop GPU implementations of it later this year.
Windows 95 (OSR2), Windows 98, Windows 98SE, Windows NT, Windows 2000 and Windows ME users can obtain Open GL drivers by any of the below methods.
Windows NT 4.0 and Windows 2000 are included with Open GL v1.1 libraries, but if Open GL drivers are needed for a software game you must obtain the Open GL drivers by following the above instructions.
As the biggest graphics event of the year this show has become the Khronos Group’s favorite venue for delivering news about the state and development of Open GL, and this year’s show is no exception.
This week will see Khronos delivering news about all of their major Open GL initiatives: Open GL, Open GL ES, and Web GL, taking to the show to announce a new version of their core graphics API while also delivering updates on recent advancements in its offshoots.
Kicking things off, we’ll start with the announcement of the next iteration of Open GL, Open GL 4.5.
As has become customary for Khronos, they are issuing their yearly update for Open GL 4 at SIGGRAPH, further iterating on the API by integrating some additional features into the Open GL core standard.
The APIs continue to have their corner cases where similar features are implemented differently, with the addition of Direct3D emulation features simplifying porting by offering versions of these features that adhere to Direct3D’s implementation requirements and quirks.
Finally Open GL 4.5 is also implementing further robustness requirements, these being primarily targeted at improving Web GL execution by enhancing security and isolation (e.g.
Meanwhile on the Web GL front, Khronos is happy to report that Web GL support is nearing ubiquity.
The web-friendly/web-safe version of Open GL has been complete for a while now, but it has taken some time for browser developers to implement support for it in to all of the major browsers.
like this one (This is my GTX 460 Card)Maybe the new version of 1.18 PTR is using some Open GL features which your video card cannot support Same here :/060E4328-EB55-4A4A-8A2E-F2997274B196Win 7 x64Integrated Video chip: Mobile Intel® 4 Series Express Chipset Family I've update the video driver but looks like it wont update open GL to the required version.
