Hi. I have an older computer from 2007 with Windows 7 Ultimate 32-bit fully updated on it, as well as an Intel Pentium M 2.3 GHz, 2 GB RAM, and an ATI Mobility Radeon X600 with the most recent Windows Update driver, which is 8.561.0.0 from Dec 1st 2008. I also have "DirectX End-User Runtimes (June 2010)" installed (had it before, and just reinstalled it anyway). And as I said, it's fully updated, meaning it also has the DirectX 11.1 update installed. I installed the newest Firefox on it, and going on `about:support`, Hardware Acceleration tells me it's available by default but it's not working anyway (either "unavailable by runtime" or "failed by runtime", saying either that WebRender failed initializing, or that it failed acquiring a D3D11 device, and no idea why, because I think I just reinstalled it with the Microsoft DX installed from their download pages(?). What does that mean? How can I fix this and get it to work? I could really use HW acceleration on this old thing. I've already disabled disk cache, and now the only issue is the high CPU bottleneck on it if I watch a video or do other rather intensive thing (even though the video is at 360p). [By the way, congratulations, this is the fastest browser I've found, and disabling disk cache and changing memory cache capacity are really very useful options, so thank you so much]. Does it help if I saw dxdiag says there was a problem with DirectShow, even though if I ignore the error, DirectShow, Direct3D and APG textures are still "Activated"? (If I don't ignore the error, dxdiag crashes) I can provide any other required information. Thank you.
