There is currently no workaround, you will have to wait for the rewrite of OBS, which is still some time away.
I will caution, however, that even when it does "work" for your system, it will likely not work well. There's no real compensating for the lack of power your system has. That graphics chip is old and not very powerful at all. Based on the graphics chipset you have, I imagine your processor isn't all that powerful, either.
