@@semyon3464 that would make me wonder if it's a motherboard issue or even if you've accidentally connected the gpu in the wrong pci slot, because I was using a Saphire Radeon RX 470 8g previously and was nowhere near that bad, and even with my current Saphire Radeon 5700XT Nitro+ I'm still using my Ryzen 2600x. Sure my system has 32 gigs of RAM for handling some rendering and image processing tasks, but unless your running 4 gigs somehow or have a PC loaded to the 9's with malware that doesn't make any sense at all. I had Alyx fully Playable on mid to low settings with no resolution change on the rx 470 so your current problems sound like a major system issue, if you have a m.2 drive installed I'd make sure that that specific m.2 slot doesn't turn off PCI-E lanes on one of the slots tools that would cripple preformance especially if you accidentally put tge GPU in the wrong slot

[@Nachokinz]

@@nemodynia The calculation reaching the result of 818 only accounts for what an 8080 could accomplish if somehow clocked successfully to 3.9 ghz. Keep in mind that modern processors are also able to accomplish more per clock cycle, intructions per clock (IPC).

@@nemodynia they absolutely are millions of times faster. A modern CPU core can do multiple things per clock cycle. Also note that a modern CPU has multiple cores that do multiple things per clock cycle and it's pretty obvious that they are faster. How do you think newer generation CPUs are able to beat 10 year old CPUs even if the older CPU has a higher clock speed with the same core count?

This proves that computers can be milked to their full potential. If this is possible 7 years ago from this comment it was possible back in the 1980's too. If this 8088 is able to render video and play audio at the same time with minimal chopping can you imagine what today's machines can do if we sat down and wrote programs with hardcore efficiency in mind?

[@mukansamonkey]

Eh no, that's not what's going on here. This isn't a video file being rendered, it's an executable doing direct modifications of the video memory. Basically the creator broke down the original video into a series of transitions between each frame. Which pixels change. Then made a long series of calls to the video memory, changing those pixels at set points in time. Some further optimizations involved like which order the changes happen in. But in the end it's just switching bits in video memory directly.

[@wheezybackports6444]

@@mukansamonkey which means it's rendering it out anyway. It's just in a different format. You just said it in a verbose way.

[@mukansamonkey]

​@@wheezybackports6444 I went and read the tech notes by the creator, Jim Leonard. No rendering is performed by the executable being run here. The rendering is done in advance. Followed by: Downscale to appropriate size Dither down to desired colorspace Create a delta of the pixels that change between frames Compact that list into groups, like "all pixels between offset xxx and yyy change to 1111. Sort groups by size+some other stuff Compile instruction set consisting of the changes in order plus the I/O handling, logic for dropping the smallest groups, etc. All of that is done in advance. The only thing that is happening during this video is commands changing registers in video memory (well plus sending data to the audio card). In fact, the big optimization between this project and Jim's previous one, is that it doesn't even bother with writing to the video buffer, it sends commands directly to the video controller. And none of this is relevant to optimizing higher quality video. I mean, steps 2 and 3 amount to "lose most video data", and the remaining steps are "spend a ton of processor time arranging the data in a way that an extremely limited system can load it into video mem without pausing (just introducing errors instead)". It really has nothing at all to do with rendering. The rendering is done on a far more powerful machine.

@@mukansamonkey still hardcore efficiency. These machines would not be able to work this way otherwise.

[@valenrn8657]

IBM PC clones are the dominant desktop micro-computers. IBM lost control of the X86 PC due to many factors such as pricing and evolving standards e.g. E-ISA/VL-Bus/PCI vs IBM MCA. IBM-inspired E-ISA (32-bit ISA) killed IBM MCA just as Intel-inspired AMD's X86-64 killed Intel Itanium. 32-bit ISA and 32-bit VL-Bus slot were replaced by PCI. All x86 PCs still have the beating the heart of the 8086 instruction set and most PCs prior to UEFI Class 3 still have "IBM PC" compatibility i.e. retro machine built-in. AMD X570 motherboards are UEFI Class 2 with a compatibility support module (CSM). The 8086 still exists as X86-64. Intel 8088 is just an 8-bit external bus version of 8086. AMD Zen 4 Genoa has 12 memory 64-bit DDR5 channels i.e. 768 bits external memory bus, not including PCIe lanes. PC/104 embedded ecosystem still has ISA slot support.

[@CreeperOnYourHouse]

tl;dr The video isn't a video, it's an executable with a long list of instructions the CPU blindly follows to make the screen look how it should. If you look at the write up behind it, what happened is that he realised he didn't actually need to have the CPU process video files, which would take up way too much memory and time to process. Instead, what he could do is have an "encoder" that simply created a list of instructions the CPU needed to perform in an executable, which would then change the screen in the optimal places at the right time in the right way so that the areas that changed the most from one frame to the next would change first, and so on and so on. It's a video, but the CPU isn't actually playing a video. It just blindly changes the video memory so that it works. By tying the timing to the packets sent to the soundblaster, he could get the audio and video to sync up without actually needing a video file which had 2 separate tracks, just 1 endless stream of info. trixter.oldskool.org/2014/06/19/8088-domination-post-mortem-part-1/
