Until now, beta users that are looking for minimal HW requirement are redirected to the URL above that is specific to FF 3.6. In that page, there is no info about graphic cards. Users must be informed of the minimal HW and driver requirement of their graphic card in order to have HW acceleration available in FF 4.0.

Benoit, Can you provide requested information?

Here is my proposal for Windows: To have full HW acceleration available: * OS: Windows Vista, Windows Server 2008, Windows 7. * Graphic cards: NVIDIA : any cards with driver version 257.21 or above. ATI/AMD: any cards with driver version 10.6 or above. Intel : G33, Q33, Q35, GMA 3150, GMA 500, Mobile 945GM Express Chipset families with the latest Intel driver version. B43, Q43, Q45, G41, G43, G45, Mobile 4 Series Express Chipset, HD graphics families with driver version 8.15.10.2202 or above. Other cards: Not available by default.

Please note that HW Acceleration does not works on G33, as well as G965. The relevant bug for G965 is https://bugzilla.mozilla.org/show_bug.cgi?id=604974. I am pretty much sure that HW is also not working on Q33, as it has similar GFX Architecture to G33.

Comment 2 takes only into account the graphic driver blocklisting for D2D/D3D. It must be refined according to min graphics HW requirements that I don't know.

Would perhaps the ATI/NVIDIA phrase "any cards with..." from comment 2, actually be better as "any DirectX 9 or higher cards...", seeing as Dx8 and below aren't supported?

> Would perhaps the ATI/NVIDIA phrase "any cards with..." from comment 2, > actually be better as "any DirectX 9 or higher cards...", seeing as Dx8 and > below aren't supported? This page must be accessible to all users. How many users know their GPU DirectX version? In addition, the required min driver version implicates that the GPU directX version is higher or equal than 9. > It must be refined according to min graphics HW requirements that I don't > know. Here they are: 4096x4096 textures, DX9/10. The min texture size add these restrictions: * NVIDIA: at least NVIDIA 7 series * ATI: at least ATI X1xxx or 6xxx series * Intel: at least GMA 500 or GMA X3000 (SM 3.0 HW, http://software.intel.com/en-us/articles/intel-gma-3000-and-x3000-developers-guide/, http://en.wikipedia.org/wiki/Intel_GMA#Specifications) So comment 2 becomes: To have full HW acceleration available: * OS: Windows Vista, Windows Server 2008, Windows 7. * Graphic cards: NVIDIA : any cards with driver version 257.21 or above. ATI/AMD: any cards with driver version 10.6 or above. Intel : GMA 500, 600 with the latest Intel driver version. B43, Q43, Q45, G41, G43, G45, Mobile 4 Series Express Chipset, HD graphics families with driver version 8.15.10.2202 or above. Other cards: Not available by default. Note: If bug 627968 is not going to be fixed, remove GMA 600. If bug 628129 is not going to be fixed, a line about dual GPUs that does not support HW acceleration must be added.

(In reply to comment #6) > This page must be accessible to all users. How many users know their GPU > DirectX version? In addition, the required min driver version implicates that > the GPU directX version is higher or equal than 9. Fair point. On a different note, the 6200 will be blocked in/due to bug 612007, so: "NVIDIA : any cards with driver version 257.21 or above." ...presumably needs to be adjusted to exclude the 6200 and any other cards that have been blocklisted in a similar manner. Note: I'm using 260.99 with the 6200, so saying just "driver version 257.21 or above" isn't enough to indicate this card is excluded.

What a about the maximal resolution for hardware acceleration?

(In reply to comment #6) > Here they are: 4096x4096 textures, DX9/10. > The min texture size add these restrictions: > * NVIDIA: at least NVIDIA 7 series 6 Series cards are DX9c which requires a minimum maximum texture size of 4096x4096 (and Works on My Machine (tm))

> What a about the maximal resolution for hardware acceleration? I don't think there is a min or max display resolution requirement for hardware acceleration. > 6 Series cards are DX9c which requires a minimum maximum texture size of > 4096x4096 (and Works on My Machine (tm)) OK. But this does not change the proposal in comment 6 as GeForce 5FX series (below 6 Series) are legacy GPUs that don't support 257.21. 6200TC is an exception that should be added.

Need to ask layers gurus (Roc...) about that. Not sure if it's a matter of display size or browser window size or images size.

Correction: Vista and some (all?) Intel device drivers don't cope well (see bug 605053). ;-) At least, "Mobile 4 Series Express Chipset" (bug 605053 comment 23) and "HD Graphics" (bug 605053 comment 26) - both probably due to incomplete drivers (bug 605053 comment 22) on Windows Vista *only* - Windows 7 works fine.

I'm not sure right now whether Firefox will fall back to software in that case.

> What's when the vertical or horizontal resolution is higher than the maximal > texture size? There is currently no monitor that singly displays at these levels (higher than 4096x4096).See http://en.wikipedia.org/wiki/WQSXGA#Hyper-extended_graphics_array

Here is another attempt (Windows only): To have full HW acceleration available: * OS: Windows Vista, Windows Server 2008, Windows 7. * Graphic cards: . NVIDIA : any cards with driver version 257.21 or above. . ATI/AMD: any cards with driver version 10.6 or above. . Intel (on Windows 7 and Server 2008): GMA 500, 600 with graphics driver version 5.0.0.2026 or above. B43, Q43, Q45, G41, G43, G45, Mobile 4 Series Express Chipset, HD graphics families with graphics driver version 8.15.10.2202 or above. . Other cards: Not available by default. Graphics driver blocklist: . GMA 600, all graphics version driver versions. Reason: new card not tested (see bug 627968) . NVIDIA 6200TC, all graphics driver versions. Reason: black & white horizontal bars/glitches in page content area when scrolling (see bug 612007) . Intel GPU if dual GPUs, all graphics driver versions.

Any Graphics driver in > https://wiki.mozilla.org/Blocklisting/Blocked_Graphics_Drivers I get only D3D9 acceleration on a NVIDIA GeForce Go 7300 (10de:01d7) with driver version 259.47 on Win7 but it's not listed there. Maybe it should be mentioned somewhere that no D2D implies no D3D10.

Reason: graphics driver > version numbering not compliant with Intel's one (see bug 628129) Well, in certain cases only. Blocking only occurs when: * either the registry is self-inconsistent, in that it reports the Intel vendor ID and the other non-Intel driver version; * or the main GPU reported in the registry is the Intel GPU, and the Intel driver was mis-installed, which is something we block anyway regardless of dual-GPU. (Right?)

> (Right?) Almost correct because even if the registry is self inconsistent, if it is not the used GPU while you start Firefox, it is not blocklisted and as a consequence Firefox crashes after the GPU switching (bug 635464).

The HW acceleration of my Intel(R) G45/G43 Express Chipset was disabled by my last FF 5 beta update, see (about:support bellow).

Does the bug persist with a new profile? Type a command line like this: firefox -P -no-remote

oh ok :-)

Fernando, you don't use the same computer, this one has an obsolete Vista graphics driver that it is blocked. In the future, for that kind of problem, use the support forum instead: https://support.mozilla.com/en-US/questions/new

Ok, I just wondered because this driver wasn't blocked in previous FF versions, and a didn't found any bug here commenting/documenting this decision .

@ Scoobidiver: his chip is in the "GMA 950" family, and on Vista, according to your table that we still use (since Firefox 4) for blacklisting, the minimum required version is 7.14.10.1504, exactly the version he has. So it's not clear to me why he's getting blacklisted. @ Fernando: the fact that it's intermitten could be either a bug in the driver, or on our side. Have you tried updating this driver? Does this make a difference?

Oh but Scoobidiver is right that this is a different computer with a different GPU. So the last thing to understand is why you're not getting acceleration on the Intel GMA 945. Do we even know that acceleration works on such an old Intel chip? For sure it would have to emulate some features like vertex shaders in software.

(In reply to comment #32) > @ Fernando: the fact that it's intermitten could be either a bug in the > driver, or on our side. In fact the previous problem reported by me happened on other computer (sorry by the confusion, my bad :-( ). The fist problem (Intel(R) G45/G43 Express Chipset) doesn't happened any more. The second problem (computer) isn't intermittent, it started with FF 6, with FF before V6, GMA 950 has HW acceleration enabled. > Have you tried updating this driver? Does this make a difference? Version 7.14.10.1504 is the last version available for the driver, so I will try to reinstall it, and post here the results.

When I updated to FF 6 b4 some parameters changed now Direct Write is enabled, bud Direct2D continues blocked.

With Windows 8, a lot of these old graphics cards are getting new drivers from Microsoft. You may want to retest. Especially since some proposed changes are actually going to slow down software rendering, so we need to get as many people on hardware rendering as possible. If Windows 8 can accelerate my card--including Internet Explorer, I don't see why Firefox can't.
