Uhh, I'm not sure I buy that. I'm not a display pipe expert but my understanding is there are physically only N (2-3 or whatever) clock generators in most GPUs, hence the requirement to have...

Wouldn't it be more likely related to the sync'd clock signal stuff that was part of the original restrictions for needing a DP monitor? i.e. I imagine if you had all display-port monitors it could...

Probably is related to doing "blobby"-type occlusion type things like your googling implies.

PRT/tiled resources does not allocated pages on the fly - all the allocating/mapping is still done from the CPU between frames, etc. Hitting real page faults or otherwise stopping GPU execution to...

Even if the hardware supports haulting on a page fault like that (it may or may not, I don't know), it's likely to be reeaaaallly slow. Definitely not something you want to be doing in the middle of...

Yes, but you don't really have any good options once you run out of memory. Basically in the case of "too much transparency" you just have to drop fragments. This obviously produces artefacts and...

If a similar feature is available in DirectX feature level 12, game developers will have to modify their code to use it (i.e. it won't just automatically start working). But yes in theory eventually...

Cool, yeah I think the smoke stuff was important enough for their desired look that they wanted to implement a general path - even if slower - for other GPUs, but I don't know the details.

Anyways...

I think I corrected you on this last time (assuming they are what I think)... these are not Intel CPU-specific features (i.e. AVX2), they are Intel *GPU* features. i.e. they use pixel...

People who think any for-profit company wouldn't do exactly the same thing given the opportunity are the ones being naive.

Absolutely, I think even GPU-Z or similar can do it. GPA definitely can.

Using GW *on AMD/Intel* means that. No one is forcing you to do that, which is why I put this squarely on ISVs. I think NVIDIA would be perfectly happy for you to not run those effects at all on...
