Hi all,

I'm hoping you can help me out with some issues I'm having with FSX.

The biggest issue is that it keeps freezing all the time, for no reason it seems to just stop. Occasionaly it might crash to desktop.

Another issue is whenever I load the PMDG777 the aircraft doesn't load, all I get is the fans from the engines and a shadow.

The system is new, I only got it in October. The specs follow recomendations I received in a post I made on here last August...

Intel i7 Skylake 6700K CPU at 4GHz
16GB RAM
NVidia GTX 960 video card with DirectX 11

Windows 7 64bit. Running FSX with SP 1 & 2. Settings are set to 'high' but these were the default settings when I installed the programme so my system must be able ot run it. The post powerful addon I'm using at the moment is PMDG777 but I also have the PMDG747 installed. Scenery wise nothing major (yet), just a few UK2000 and Aerosoft Airports and FScene X.

I have also updated my drivers, I did that before installing FSX.

Cheers,

Heinz

Heinz,

Just to point out, your GPU is surprisingly underpowered for your CPU. I would suggest downloading Nvidia Inspector, and running FSX as you would, but monitoring the GPU load on the main screen of NI. I would imagine the GPU load would be at 100%, and the CPU load, visible in Task Manager > Performance, would be less than 100% on all 8 cores. If so, I would recommend tweaking FSX to be more GPU friendly, such as lowering overall graphics settings, rather than CPU based tweaks, e.g. AffinityMask.

A guide I would recommend time and time again to everyone in the FSX community is this: https://kostasfsworld.wordpress.com/fsx-software-and-hardware-guide/

Hope this helps somewhat.

With regards to the PMDG T7 glitching, I cannot help much as I do not own the aircraft myself. Have you tried reinstalling, running the installer as an admin, and disabling AV whilst installing? This doesn't guarantee anything but it can eliminate possible factors when bug fixing down the line.

Regards,

Max

Hi Max,

Sorry about my late reply. I've had a busy few days!

I have tried lowering the graphics settings but unfortunately it hasn't made much difference. It has made the triple 7 appear but its still very laggy. FSX also still crashes randomly.

Interesting what you say about the video card being underpowered for the CPU. Do you think this could be the root cause of it all?

Thanks,

Heinz

Heinz,

It's hard to say whether or not it could be the main cause, however I do think that it could certainly be a contributing factor.

Like I say, download Nvidia Inspector when you have time, and compare the GPU usage against the CPU usage to see which one is bottlenecking. 

I'd certainly recommend doing more testing with it before going out and buying a new GPU.

Keep trying things, ask if unsure, and post on other forums to get a larger audience to hear your problems for a possible fix!

Hi Max,

I have downloaded Nvidia Inspector and done a little bit of testing.

The first test I loaded up into a warm cockpit with the PMDG747, took off and randomly few around for a bit. Interestingly the GPU load peaked at only 30%, but most of the time it averaged around 20% and at one point it did dip back to 6%.

This first test only ran for about 20 minutes or so. Later when I have more time I will load a proper flight in cold and dark and do everything properly. This will allow me to see if the crashing issue is reflective on how long I'm running the simulator.

Cheers,

Heinz
