If I do this, it will come at the end of the summer. The loop emulation code will not really increase performance, it just allows the GPU to execute shaders that it couldn't before.Tomhttps://www.blogger.com/profile/03694712739809885178noreply@blogger.comtag:blogger.com,1999:blog-2414714454149868359.post-78135217166780562252010-06-09T20:49:23.038-07:002010-06-09T20:49:23.038-07:00As a r300 owner(igp xpress 1150), i`d like to than...As a r300 owner(igp xpress 1150), i`d like to thank you by doing such a job!Anonymoushttps://www.blogger.com/profile/04260004755576720552noreply@blogger.comtag:blogger.com,1999:blog-2414714454149868359.post-89899766758972234042010-06-09T01:32:34.973-07:002010-06-09T01:32:34.973-07:00What performance increase do you get with the loop...What performance increase do you get with the loop emulation patches?Fabiohttps://www.blogger.com/profile/02441404127053368651noreply@blogger.comtag:blogger.com,1999:blog-2414714454149868359.post-83503849223570465542010-06-06T12:46:26.808-07:002010-06-06T12:46:26.808-07:00I hear the i945 series also lacks loops.

Could this be applied in the i915 or i915g driver?<br /><br />Maybe you could make arbitrary looping work by returning the loop counter state to the CPU and running the shader multiple times?Anonymousnoreply@blogger.com
