I'm surprised, the last OTP chip I dealt with had a few banks of parallel xor efuses. You pop 1s to 0s on bank1 to program it, and if you gently caress it up you pop a few bits on bank2. Useful, but since it's only really available in pre-programmed but mutually incompatible configurations we ended up strapping it to default (ignore OTP) and using the bootloader to set some registers. Made buying so much easier when we could get any of the flashed SKUs when the correct one ran out. On the flipside, bypassing the OTP voltage range lock was exceptionally fun and exciting.

https://www.rockpapershotgun.com/resident-evil-village-pc-requirements Thought this was interesting, Capcom are recommending a 3070 as recommended requirements for 4k 60FPS in their new Resident Evil game with ray tracing on. Apparently a 2070 can manage 45 FPS at the same settings. Given how resource intensive raytracing currently is in other games, nevermind 4k res, do we think this is because their usage is relatively light or is ray tracing going to become more optimised in general? Is that resource hogging aspect of the tech simply because developers have yet to refine the implementation, or are we still simply not there hardware wise for it to be a viable option at 4k for all but the absolute top end cards? I wonder, now that developers have had a decent amount of time to play with the tech, whether we are going to see increasingly optimised versions of it that might give the lower end cards more of a chance at decent framerates with fancy lighting.

It's a last-gen console game with tacked on RT. Capcom aren't the sort to bother with extra high-end RT effects for the PC version, especially for something as static as an RE game where an immense amount of work has gone into hand-tuning the static lighting. Since it has to work on the weak console RT hardware, PC RT hardware will crush it. It's going to be this way for most games for the next 5 years, same way that last console generation it was easy to push games bound to 30 FPS by the awful Jaguar CPUs to 100+ CPU FPS on nearly any PC.

The RT in the PS5 demo was pretty conservative, just low resolution (1/8th-ish) reflections on the few very shiny surfaces and some extra diffuse GI detail in a small radius around the camera https://www.youtube.com/watch?v=bP4p_unwBPA&t=338s It seems to work okay for that kind of game, as K8.0 said the baked lighting holds up very well I wouldn't be surprised if they turn off the RT in the outdoor sections not seen in the demo though repiv fucked around with this message at 17:52 on Mar 22, 2021 |

Is that resource hogging aspect of the tech simply because developers have yet to refine the implementation, or are we still simply not there hardware wise for it to be a viable option at 4k for all but the absolute top end cards? There will continue to be optimizations, but people have been trying to do real-time raytracing for what, thirty years now? There are definitely SIGGRAPH papers about it from the 90s. The algorithms are pretty well worked out by now and there isn't much more you can do than throw cycles at it. Of course there are tricks and simplifications, but most of those are already implemented. Things like blending the light transport across several frames, lowering the resolution of effects, etc. The biggest leap in making raytracing feasible is DLSS, which doesn't have anything to do with raytracing specifically -- it just lets you get away with a lower-resolution rendering. And while that technology may continue to improve, you can't just make something out of nothing. You can already see the cracks in DLSS when you set it to performance mode. So no I don't think raytracing is going to get significantly more efficient as time goes on.

Harik posted:Yeah, PCIe x4 screams 'multihead'. Selling to video wall companies? I wonder if it will even support multi-head systems. It already requires custom BIOS support, that doesn't scream "tons of flexibility in system configuration" either. I read an interesting thought that maybe it's actually running DMI under the hood and not PCIe and that may be why it requires custom BIOS support...

I am hesitant to really explore this option, but given just how old my current rig is I feel it's still worth looking into: Are there are any recommended pre-built options for a new PC? I know absolutely nothing about who's making pre-built stuff, aside from like....I think I wanted Alienware when it was 2005.

The RX 5500XT is x8 and in certain cases the 4 GB versions got hammered when running in PCIE 3.0 whenever there was a need to swap data in the VRAM IIRC.

I don't know if this is still a thing that happens, but I remember years ago getting a used HP or other brand desktop with a dumbed-down BIOS. I researched it and found out it was just a rebadged MSI motherboard and was able to flash the non-proprietary BIOS onto it and it was like a new machine.

You still need to be careful with prebuilts, imo. There are lots of caveats still out there with them. If they work for what you need, i dont think anyone should be shamed for buying one, though. Just look out for stuff like: single dimm, single rank memory configs with bad speeds and worse timings, in house motherboards with no BIOS options, Realtek LAN/WiFi, trash tier dramless-SSDs and insane upsell pricing, low wattage powersupplies with custom or 12VO connectors, very bad no good cooling, GPUs that are BIOS locked to the motherboard it is with (thankfully becoming less common), and the big one these days... if it uses an in house motherboard (so not one specifically marketed as ASUS, Asrock, MSI, or Gigabyte) and a CPU without a K or X on the end of the name, you need to assume that you are going to be TDP throttled heavily and your CPU performance will be nowhere near what you see on 3rd party charts. This applies to anything Intel with 6 or more cores, and anything AMD with 8 or more cores, generally. Prebuilds often strictly enforce the Intel/AMD TDP limits on those non K or X SKUs to save a few pennies with a dinky cooling solution, and with a lot of the in house BIOS still being blue screen affairs, good luck overriding it. It is a real problem. It happens in DIY builds too, but most boards will ignore the TDP limits if you turn XMP/DOCP on, and at least you have the ability to override it if you are the type of person who would know the difference.

Some motherboards refuse to boot without a monitor attached. Probably for market segmentation reasons. You occasionally see support for headless mode added in bios updates.

Yeah, it was still common in some SFF office machine prebuilds as of the Maxwell-ish generation. They move as much as they can to the motherboard for cost/space, and that includes the goddamn VBIOS chip itself sometimes. Like I said, less common these days thankfully. Haven’t heard of it in a while, but I don’t look at tech support forums very often anymore.

Does this also apply if the GPU is plugged into a display, but the screen isn't on? I have a media server PC that's plugged into my TV, but I rarely use it through the TV directly: it's either streaming from Plex via a Shield, or I'm connected via remote desktop. Sometimes when I reboot the server I can't see anything on the remote connection until I switch the TV on and swap input to the PC. Would using a dummy plug stop that behaviour? Because it's prevented me from getting on the server when I'm not at home to switch on the TV.
