There are many things wrong with DCS. But to claim there is an issue with the p51 with no further information is laughable. I have had the p51 since it's release and there are no such issues. Only technique.

And due to this I will not be preordering. I have been bitten one too many times from ED early access. Will the Chinnok release with LODs as multiple previous aircraft have not? I couldn't help but notice there was no clip showing crew loading into the aircraft, same with the vehicle. That should be implemented along with bringing that to all the other applicable helicopters in the sim. I look forward to purchasing, when the dust has settled and it's clear what exaclty is being sold.

Just to clarify it's not just the legnth of time (and it's not just the Mosquito). The fuel cut off, or the mixture going to idle cut off, removes the fuel from the engine... So there shouldnt be any backfiring once the cut off is selected.

Just managed to fix it, I there there was a conflix with script exporting. Solved now!

Hello I keep getting this error in DCS with simshaker.. Any advise? Flying in the Mosquito.

Can someone from ED please confirm this issue (with all the merlin aircraft not just the Mosquito) is now being looked into and fixed. Please do not just close the thread as not a bug or reported. We have clearly raised an issue here and I fear just like a lot of them they fall on deaf ears. There is no question that the shutdown dynamics are wrong, even the startup ones aren't amazing. This is part of the simulation of these great aircraft, please improve it.

Looking at this, I think this is an issue with the game. We should be able to drop below the max hz of the display without stuttering and having those horrid frame timings. I now have a 4090 and whilst it is smoother. I do get those drops. The gpu usage isn't maxed out either.

Yeah i'm aware it runs with 6, hence me asking if there is anyone who could magic into running with 8!

I wonder if it is possible to get the SSA working all 8 motors on the hf8 instead of 6. Any ideas?

Sorry but as art has said, is 100% unavoidable if shutting down as per SOP in any merlin aircraft in dcs. So you might be missing the issue that we are highlighting.

I don't think we are questioning the shutdown procedure. The point being is that when you still get backfires and splutters when you shouldn't which is an incorrect modelling/simplification of the shutdown process, which applies to all the merlin aircraft at minimum.

Yeah agreed. In other situations with the carbed engines, I have had to shutdown an aircraft by going to full throttle with the mixture in cut off (as it kept running). Which killed the engine as it got too much air. My point being is that it it seems the dcs engine simulation is actually a lot simpler than I initially thought. What is impostant though as stated here, the current shutdown script is wrong. Its a shame that this is the case, as like you I rarely actually fly combat and just enjoy the flight model and messing around in VR. I wish the engine simulation was far more realistic in many many ways, this startup issue along with the abnormally high oil pressure in startup playing a big part in my irritation with the sim. I hold out hope that one day these things will actually be fixed.

This is one of the many engine issues I have tried to raise in the past which seem to be ignore. As stated above this issue spans into almost all of the warbirds (mainly the merlin engined ones). When you shut the engine down you should cut the fuel off, in the aircraft it is usually mixture cut off or similar. In DCS it is as if there is still fuel getting into the engine making them splutter and backfire. Completly unrealistic. The only way to make it cut off correctly is by turning the maggs off which is not realistic.

Still would like this to be actioned. Following on from this. It should be possible to prime the aircraft off field without a ground crew, since there are 2 crew members and a door...

Not locked to 60fps, my headset is 90hz (reverb g2) so I have locked fps to 90. I think it just happened to drop to the nice round number of 60fps. I'm not going to loose sleep over this as I'm sure when the 4090 shows up ill be getting some gains either way.

nullHAGS disabled, It appears I now have higher FPS however the game is still bouncing between CPU bound, main thread and rendering thread. Given my gpu load is essentially between 97-100 I would think that it is still limited by the GPU. Anything else I can do to get the most out of my CPU in dcs?

Thanks for your response, so far I have: Undervolted and limited the power draw of my cpu so it doesn't burn a hole through the floor. It is able to run at around 5ghz fully loaded. In DCS the cpu load isn't that big so it will be able to maintain 5.5ghz. I'm using project lasso and enabled bitsum high performance which has prevented the cores from parking. One thing I'm not sure where DCS stands currently is hyperthreading on or off? The one thing I haven't yet done is HAGS off. Just going to try that now and will report back. It isn't like I haven't gone into this without trying to change settings and optimise the cpu. Just seems very surprising that it says this, I posted on reddit as well and it has been suggested that the overlay could just be wrong. I have a 4090 on the way tomorrow and I'm hoping that it does actually allow for some improvement. Fingers crossed.

Having just purchases a 14700k, I can tell you that it isnt much better.

Unfortunately, I already have motion reprojection turned off. I was quite surprised that it's showing that the cpu is the limiting factor still. Looking at my frame time graph above my assumption is having all those jumps is not a good thing. This is also a completly clean install of DCS, so I am truly at a loss as to why performance isn't better.

Hi all, I have just upgraded my pc (partially) 14700k 64gb, DDR5 6400mhz 2080ti To my surprise when I launched DCS it says I am still CPU bound. I have set the cpu affinity in project lasso to P cores only. Also my cpu usage is surprisingly low. Any support on this would be greatly appreciated. I do plan on getting a 4090 soon, but if im already cpu bound im already at a loss!nullnull

Hello, sorry if this isn't the appropriate thread. I'm trying to either replace my old broken gametrix jetseat with a jetpad or something that will work just as well with this software. Is it currently possible to purchase any such thing currently given sanctions etc? I'm in the United Kingdom.

This is due to the LOD models on the aircraft. There is a similar issue in that some aircraft (mostly the F18) have very jarring pop in effects of the lights. During the daytime they are brighter than the sun, this has been an issue for about 2 years now.

Hello, this is still an issue. Today I launched dcs for the first time in a while. Started the p51 in 10°c and the oil pressure went above the red and up to 200. Obviously in the real world this causes blown seals amongst other issues. But more importantly this is not how the oil pressure should react. In reality it should be a slower rise, and considering I never went above 1000rpm on startup it shouldn't go over the red line. Once again I am asking to please reassess this oversight. You have the video above showing another p51 starting up and can see a realistic oil pressure rise. Obviously Nick and the rest of the TFC pilots would tell you if the oil pressure rises like it does in some of the dcs pistons they would be heading back into the hangar.

Excellent, thanks for the explanation. I assumed if it was modeled that way in the sim it's because of a different set up to modern day. Thanks!

Thanks, I thought I had seen it in the past reported as not a bug. Hence my question. The way I understand the boost coil would only work if the mags are actually turned on. Watching P51 startup videos on YouTube like kermit weeks (I know not great to use as a source but hey ho) they always count so many blades before turning the mags on, in DCS you can't do that since the engine catches well before that. To me it seems like some weird logic that that is how it is wired up. Not saying it's wrong if it is proven, but would appreciate some documentation actually showing that this is correct.
