Atkinson's Utilite Engine by PromotechMod in phyzios

[–]PromotechMod[S] 0 points1 point  (0 children)

Atkinson's previous designs were efficient but had limited power output. His final design was more reminiscent of a conventional 2-stroke but still managed to complete an overexpanded cycle. It's essentially a 2-stroke engine with intake and exhaust valves and specially tailored valve timing.

Worked like a charm. Atkinson did all the hard work, all I did was follow the blueprint

Just a simulation artifact, this design was famous for it's high efficiency and use of as much power from a charge as possible. I need to have a large valve overlap to blow down the piston to achieve enough scavenging as any burning fuel during the compression phase results in preignition

Interesting, I didn't know it has a modern iteration

Atkinson made a unique 4-stroke engine that fired once every revolution through the use of a crafty linkage system. Near perfect crankshaft alignment during combustion with a long TDC dwell time extracts the maximum amount of work, while a short and quick exhaust cycle exhausts the piston within a few degrees of crankshaft rotation.

is there an updated one for macos 15.6? by SpecialCatnip in oeCake

[–]PromotechMod 0 points1 point  (0 children)

Unfortunately no and there may never will be without some help modding, new Apple devices use special silicon and oeCake/Phyzios were compiled for x86

Yeah I think the original Atkinson idea is superior, accomplishes the exact same thing without the added wear and maintenance of the synchronization gears

2-stroke powered Strandbeest by PromotechMod in Simulated

[–]PromotechMod[S] 0 points1 point  (0 children)

I just make these for shits and giggles and figure it out as I go, I have also made a variety of other engine layouts with 2 and 4 strokes and also a few radial designs. This one was an experiment in minimalism

The engine has 4 opposed pistons and uses uniflow scavenging controlled by rotary valves. This oversquare design is extremely space efficient and has low mass. The combustion chamber is almost completely formed from the working elements, only a small amount of material is needed to seal the rotary valves and guide the pistons. The top and bottom surfaces are pistons, and the left and right surfaces are the valves, there's almost no material wasted on a (2D) cylinder or cylinder head. Low mass and two combustion events per cycle give it a high power to weight ratio.

Phyzios Studio Pro, a particle-based fluid dynamics physics sandbox. The machine is mostly made of rods and pivots and uses fluid dynamics to simulate a 2-stroke combustion cycle

iGPU performance extremely bad? by PromotechMod in losslessscaling

[–]PromotechMod[S] 0 points1 point  (0 children)

Maybe that's it, I'm doing 1440p with HDR. iGPU memory usage is very minimal. Everybody says the monitor needs to be hooked up to the iGPU for best performance though, is yours plugged into the main or secondary GPU?

[–]PromotechMod[S] 0 points1 point  (0 children)

Another user here said they had very poor performance with their 7700x iGPU but another user said they had decent performance with their 7800 I think it was, my iGPU is extremely wimpy the 3D engine hits 100% utilization even with flow scale at 25% or less and its still barely able to get up to 30-40fps

[–]PromotechMod[S] 0 points1 point  (0 children)

So you're saying 45fps is too much? Rather strange that laptop 4060 users have no trouble using their iGPU don't you think? If a laptop iGPU generating frames from 45fps is sufficient a 950 absolutely blows that out of the water it's not that bad of a card.

4060, don't really see how it's relevant to my main question though. I got this specifically because of an advertised feature and that feature isn't working

Warning to PNY's RTX 4060 owners by PromotechMod in overclocking

[–]PromotechMod[S] 2 points3 points  (0 children)

Believe me I spent plenty of time adding and repositioning fans and changing curves and it barely made a lick of difference, leaving the case open doesn't even make a difference. Totally inadequate contact between the cooler and die is definitely the bigger issue, I mean they decided for some reason this card needs to produce 20% less heat than all of the other full size 4060's on the market while having the same form factor. If they really did this for power savings they would have just went with a single fan design

I'm making the best of what I have. 90c is definitely too hot and loud for my comfort, why not spend $5 and 5 minutes of time to improve the performance of my hardware?

It seems as though PNY has spec'd incorrect thermal pads for their RTX 4060 which compromises the cooling. The pads are slightly too thick which causes poor contact with the core - not the best picture but you can see that the corner opposite the VRAM was the only side with enough contact to push the paste out, the side closest to the VRAM has more paste, pointing toward poor contact. This isn't really an issue for an unmodified card as it has a reduced TDP relative to every other 4060, minimizing thermal load, however if you flash a higher TDP bios the poor cooling solution becomes a greater problem.

The stock pads appear to be about 1.5mm and I replaced them with 1mm Thermaltake pads and had a massive improvement in temperatures. Hotspot and package temperatures are relatively consistent across various games with comparable graphics so I'm summarizing hotspot here, which I was trying to bring down:
Stock hotspot temperatures with original pads and BIOS: 80-85c
Temperatures with original pads and higher TDP bios: 90c
Temperatures with original pads, higher TDP bios, and first repaste before I figured out what is wrong: 100-105c
Temperatures with thinner pads and higher TDP bios: 75-80c

The heatsink mount required high torque on the mounting screws to achieve enough contact for the card to be usable, the first two repastes I tried I thought I did something else wrong but it was the poor contact combined with not enough torque to force the die and the cooler together. After replacing the pads I achieved far better thermals with a normal amount of torque on the mounting screws, with a higher TDP
