Intel HD3000

[Tone]

Working with the 4.0.1 Trial, Win 7/64, i5-2500K, 16gb ram. Have HD3000 graphics which seems pretty perky with Resolume, except that the dual screen control seems to go haywire fairly often, or I completely lose my cursor and have to Ctrl-Alt-Del to bring up the task manager, thus revealing my cursor again, but only until I quit out of the task manager, or I actually kill Resolume in Task Manager.

I have dual 1920x1080 displays setup as "extended desktop", the only other choice being "clone."

Have tried Resolume on a very similar system with a Nvidia 8300GS, "extended desktop", and none of these problems occur, although the older Nvidia card is just too slow.

So... is there something I'm doing wrong with the HD3000 setup? Is this graphics adapter not supported? Would be a shame, as the Sandy Bridge integrated HD3000 graphics seems fast enough, just not dual screen capable with Resolume, although many other programs (like Premiere) work in dual screen mode on this configuration.

The documentation is a bit loose on graphics adapter requirements.

Basically anything better than a ATI Radeon HD 2600 or nVidia GeForce 8600 will be fine.

There's a cautionary note about cheap Intel graphics controllers in laptops, but does this somehow refer to Sandy Bridge desktops with i5/HD3000 configurations (not cheap, nor low-end, and certainly much better than the aforementioned Radeon 2600 or nVidia 8600)?

Thanks in advance for any guidance.

There are a few OpenGL extensions that Resolume needs in order to work properly, and the problem with most Intel cards is that they do not fully support OpenGL. Perhaps this can be fixed with a driver update for your card?

Yup, driver update resolved things. A bit tricky, as the latest driver is not listed in the Intel Download Center. A bit of googling finds it on the Intel site: http://downloadcenter.intel.com/Detail_ ... 15.10.2622, version 15.22.54.64.2622, dated 1/21/2012.

I was a bit surprised that Resolume performed quite well with this shared memory graphics configuration. Running 3 layers of 720p video at 720 output, including perspective output mapping in Arena I'm getting about 60 fps (no global effects).

Thanks for the quick response.
