So, when it comes to older models, on older internal GPUs, we’ve had dot product acceleration (DP4a) for a while now. Microsoft has enabled this through Shader Model 6.4 and above and on all these platforms XeSS will work. And as I said, the objective is to maintain the fidelity of your render and achieve smooth frame rates. It might not be as fast as matrix acceleration, but certainly meets the objective. So even without Matrix acceleration you can go quite far. Karthik Vaidyanathan (KV): " Nvidia has had this I think, since Turing and AMD has this now on RDNA2. Intel’s technology will be available in two variants: XMX-accelerated, exclusive to Intel Arc GPUs, and DP4a based, a special dot product acceleration supported by Microsoft Shader Model 6.4 enabled GPUs, including NVIDIA Pascal, Turing, and AMD RDNA1/2.

AMD recommendations are allowed in other threads. Commenting on a build pic saying they should have gone AMD is also inappropriate. i7-9700k vs i9-9900k?) recommendations, do not reply with non-Intel recommendations. Rule #4: Give competitors' recommendations only where appropriate. No religion/politics unless it is directly related to Intel Corporation Rule 3: All posts must be related to Intel or Intel products. Rule 2: No Unoriginal Sources, Referral links or Paywalled Articles. If you can't say something respectfully, don't say it at all. This includes comments such as "retard", "shill", "moron" and so on. Uncivil language, slurs, and insults will result in a ban. Populating this database generally requires trial-and-error and a lot of different hardware configurations, so can be difficult for the lone developer to do, unfortunately.Subreddit and discord for Intel related news and discussions.

GPU WITH SHADER MODEL 3.0 HOW TO
What I have done to account for that kind of issue in the past is build up a locally-maintained "feature database" API that allows me to store information about particular card/driver failures and how to fall back to safe alternative code paths when that hardware/driver combination is present on the end-user's machine.

although this will not catch all bugs/failures.
GPU WITH SHADER MODEL 3.0 DRIVER
This is much rarer these days than it used to be, but in these cases you can't really trust the hardware or driver anyhow and will have to "do it yourself." One way to do this is to simply try to create something using SM3 and see if it fails. This is because, as you alluded to, it's possible for cards to lie or for there to be driver bugs that effectively render particular hardware/driver combinations "non functional" (or at least broken in a fashion you'd want to work around). You'll note that I said "should be guaranteed" in a few places. Below the 10_0 level you have some odd 10Level9 differences to take into account - the upshot for you is that you have to use odd shader model designations like vs_4_0_level_9_1 in some (perhaps all, we're getting into territory I haven't explored much in practice) scenarios. If you're using the 10_0 feature level or greater, you should be guaranteed SM4. For D3D11 (which I'd recommend over 10, since it should be the case that you can use 11 if you can use 10) device capabilities are categorized into feature levels. All four are described on the linked documentation page.įor D3D10 you should be guaranteed SM4. Of interest to you concerning this problem will the fields in the resulting structure called VertexShaderVersion and PixelShaderVersion as well as possibly MaxVertexShader30InstructionSlots and MaxPixelShader30InstructionSlots. This will give you a structure containing a lot of interesting information about what the hardware supports. If you are using D3D9, you can query for device capabilities reported by your card using the IDirect3D9::GetDeviceCaps method.
