Yes, of course, I know, but the CPU is only used to around 15 %... That percentage is an average of the load of the various cores of your CPU. To have a more precise indication you should look for the load of each core separately, as bpieke pointed out. For this purpose the Windows built-in task ma...

Yes, that was my understanding too. I was just wondering, why not completely replace fibers with threads. What are the features that make fibers desirable, despite the fact that they can't be executed concurrently thus generating a potential bottleneck in the CPU? It's just a technical curiosity fro...

Hi all, After replacing my old PC for a new one, I've spent some time messing up with the FIBER_FRAME_TIME_FRACTION parameter in the prepar3d.cfg file, following various suggestions found around the internet. Since I have a little background in software development, I wanted to know more about fiber...

The question assumes that the transition to 64 bits and dx12 allows for massive draw calls, which does not consider many factors. First question: assuming that the performance of the graphics engine of P3D may be improved, is the number of draw calls its main problem? Do not forget that P3D is an ex...

This has been a long standing issue, and is inherited from the good old FSX. I notified MS about this several times, but my notice went basically unheard. The fix is simple, the pitch of the engine sound shall be tied to the propeller RPM, not to the throttle position. This can be easily verified us...

Very same issue here, P3D v3.2 (installed from scratch, no update from previous v3.x), ASN latest build, REX4 SP6 + all hotfixes. Since two days, with no forewarning and without doing anything special in P3D or REX or ASN, the low level clouds are not displayed. Any other clouds are OK, visibility a...

That topic is about AMD driver crashes, not Nvidia. I've been using P3D v3 with the latest 3 releases of Nvidia drivers (two 358.xx and now the latest 359.00) without issues (except for a single - so far - CTD due to the infamous MSVCR120.dll error, but there is a dedicated thread for that). So I th...

I also have this problem, AI traffic set to zero, no packages installed that may affect AI, so it is unlikely that this issue is related to AI aircrafts.

Hi all, Today I had my first CTD due to the MSVCR120.dll since I installed p3d v3. I didn't make extensive tests to see whether the failure can be linked to some add-on in particular; what I can say is that the last changes I made to p3d before the problem came out were the installation of FTX Globa...

Just to add to my situation, I also tried to: Clear the shader cache (I didn't think it could have any impact on my issue, but you never know...) Uninstall all the additional liveries of the PMDG Aircraft (I read somewhere that corrupt liveries could cause issues like mine) Nothing worked. At this p...

Hi all, I've searched the forum but was not able to find anything that could be similar to my situation, so I post my case here. If there are any existing posts that suggest a valid fix, I apologize in advance. Here is the problem. I have P3D v2.5, the add-ons installed are: Dash-8 by Majestic 777-2...

<t>Well,<br/> <br/> if you are reasonably confident that the only relevant change was the installation of Norton 360, then you may try to temporarily disable it, or even uninstall it completely, and see if P3D works again. If this is the case, I think the most obvious fix would be to opt for another...

<t>Henry,<br/> <br/> if by "having a bit of trouble" you mean performance and smoothness, probably you are simply pushing your graphics card beyond its capabilities. The GTX660 was already considered a mid-range product at the time it was initially released; it is not a graphics card intended to run...

<t>Issues like these usually appear when you have a faulty RAM or are overclocking too much.<br/> <br/> As a stability test I suggest you to try Prime95. It is an utility created for a completely different purpose but it offers a built-in stress test for both CPU and RAM. Let it run for a couple of ...

Don't know if this may be of any help, but did you try to execute P3D as administrator?
