Thats not a C++ runtime missing error anyway, the error is in the intel graphics driver. Recommend updating that directly from Intel.

Do you have an Error Diffusion dithering option enabled? They require Direct Compute. I have never needed to install any pre reqs for madVR, even on new Dell laptops from work.

Your error looks like a driver crash, not part of madVR. I very much doubt it is missing or damaged runtimes used by madVR, but it might be something used by the GPU driver. You could try turning off shader caching in the GPU drivers too.. given the path name.

It's a debug message from Intel drivers

Supr Thx guyz, all fixxed, uninstalled and reinstalled latest intel Gfx drivers.

why Dell d00 dis'.. terrible outta dabox Xperience.

Thermal throttling, wrong screen color temperature, driver problems, bloatware crashing, Dell advertisement software informing me how poor I am , and telling me I couldn't afford their more expensive product..

Does anyone have weird issue with madvr in potplayer? I recall a user reported issues a couple of weeks ago, the issue I'm having is randomly delayed 2 frames. So I had to switch to mpc-be again.

I returned the 5700 and got a 1660 Ti. With the same settings rendering time is very close to 5700 but the present time is now only 0.1ms, there is no more presentation glitch.

How does madVR's 1080p > 4K upscaling compare to a legitimate 4K release? I'm starting to suspect I wasted my time with these enormous files...

Upscaled 1080p -> 2160p does not have HDR. So, native UHD is going to, by nature, almost always look better than even an upscaled 1080p. Having said that, depending on what settings you use, e.g. NGU sharp High or Very High for luma upscaling, it looks absolutely fantastic. Still, by and by, I prefer the native UHD when it's available.

Hi guys, just wondering, at what point is a PCI express 2.0 slot going to be a bottleneck for MADVR with a new PCI express 4.0 card like a 5700xt, if at all?

it's currently not working properly.

PCIe 3.0 can barely do UHD60 and PCIe 4.0 interface is only double the speed so it shouldn't be able to do FUHD60.

so PCIe 2.0 is already a bottleneck that's where native hardware decoding comes into the mix and that doesn't care even PCIe 1.0 is a total over kill for that.

so PCI express bandwidth is currently irrelevant, it makes no different whether you put a 4.0 PCI express card in 2.0, 3.0 or 4.0 slot, for MADVR?

I don't understand why it PCIe 3.0 or PCIe 2.0 are a bottleneck for that pupose.
HDMI 2.1 is capable of 48 GBit/s which is about 6 GByte/s -> sufficient for 8K 60fps but with DSC Video compression
PCIe 2.0 is about 8 GByte/s for 16 Lanes
PCIe 3.0 is about 15,x GByte/s for 16 Lanes -> sufficient for uncompressed 8K 60fps 10 bit 4:4:4 (11,2 GByte/s needed)
PCIe 4.0 is about 31,x GByte/s for 16 Lanes -> sufficient for uncompressed 8K 60fps 10 bit 4:4:4 (11,2 GByte/s needed)

But only if you have a Mainboard which has full 16 Lanes on the PCIe slot.
Some Mainboards use full size slot but only half of the pins is physically there. This can be an issue.
Here is a calculator of uncompressed videostream sizes per second: https://www.extron.de/product/videotools.aspx

Note:
Bit vs. Byte
Number of PCIe Lanes: 1 / 4 / 8 / 16

as long as native hardware decoding is used.
subtitles use a lot too.

because they are in real life tests. back in the days madshi created a tool to measure "copyback" speed on GPU. we got ~120 FPS with PCIe 3.0 with 1080p. the infamous AMD nnedi3 copyback bug (and they where still massively faster).
there is still the issue on how the video is encoded/stored:
https://docs.microsoft.com/en-us/win...-video-formats

Quote:
The 16-bit representations described here use little-endian WORD values for each channel. The 10-bit formats also use 16 bits for each channel, with the lowest 6 bits set to zero, as shown in the following diagram.
and well subtitles i have no clue if they are compressed or not.
UHD 60 is currently as far as you can go with copyback. maybe it is the latency we don't know going over UHD 60 make huge problem.

the 16x bus is directly connected to the CPU for a long time now.
the PCIe 16x slot with mechanical 8x and usually electrical 4x are usually connected to the chipset. you have to do a really good job in finding a new proper board that doesn't have a direct CPU 16x slot for many years now.

I'm convinced the real bottleneck is in the system platform (RAM) and/or the software, not the bus interface itself which is way faster than any uncompressed video you could send over it. Of course it's no help if you're stuck with PCIe 2.0 (and old system platform), but I'd be very interested in a benchmark of copyback with a 5700 on X470 and X570, to see if the bottleneck is the bus or the system RAM. Has anyone done that?

I hope madshi will implement black bar detection and film mode on the GPU now that Envy is coming out, that would help it immensely not having to do copyback on there (there would still be the problem of deinterlacing with D3D11 native on the PC version, and software support like that JRiver UHD menu thing).

Edit: that talk about future-proofing and "going over UHD60" presumes that 8K is going to become common anytime soon. I don't see that happening in the near future, not on the PC anyway. I'd watch an UHD Blu-ray over a bit-starved 8K online stream.

i switch from PCIe 3.0 ddr3 1600 mhz to PCIe 4.0 ddr4 3200 mhz and i got worse results for copyback.
