Hunting an FPS loss

Recommended Posts

Sorry for the poor title, but its pretty much my issue.

 

Running P3d v4.5 with active sky and REX sky force, I found a huge FPS loss when it comes to the detailed clouds option. Flying into TAPA last night they was a storm going on which caused my normal 30(locked) or 50+(unlocked) for that region to plummet to the single digits. I have never had any fps loss with this option being used before and normally had it on the highest setting, but i'm guessing my hiatus from playing has been very limited over the last month or two due to lack of performance.

No matter where the slider was at, low medium high, if detailed clouds option was ticked the FPS dropped down to single digits. Could anyone shed light on whats going on with this setting when I use it. 

 

TIA

Have a look what Res textures you have set in SKy force. I suggest you set them to DTX5 512 or 1014 max.

I would say that what you experienced is completely normal. I can fly at 25 fps and if there is a storm with massive cloud coverage, it will drop to 

single figures.

Hey, thanks for the replies.

 

My Cloud/cCirro type resolutions are set at 512x512

Then its all down to you P3D setting. You could try 3 layers withing AS!

When your frame rates get hammered by clouds in P3D, it's usually because your GPU is maxxed out.  If you have aggressive AA settings and HD clouds, that'll hit hard, because the GPU is trying to sharpen the edges of...fuzzy...clouds.  Lower resolution clouds helps, as well as reducing AA levels (say, from SSAA to 4xMSAA).  Higher-end GPUs also handle this load much better...a 2080Ti can deal with clouds at 4k res with impunity in situations where a 1070 will struggle to stay in double-digit territory.

Interesting Bob.

Do you have REX EF by any chance? I was also experiencing mysterious FPS loss lately, usually in overcast conditions. I use Auto mode in EF and found out that if I press "Reset manufacturing settings" the FPS usually goes back up to normal for a short time but when EF starts doing it's thing again it goes back down again.

Agree, i have one spare 2080TI that i dont used, i put it in the sim pc ( better to use it than laying in a drawer) and start run SLI with the 2080Ti , the only difference is in really bad weather and  at night. run Rex EF and  2048HD clouds ( shall test 4096  think it shall work ok) res 4K , AA 4SSAA.

the difference is similar to 2 x 1080TI SLI vs single 1080TI not as much but close need more cpu power , i know that you run SLI with 1080TI as me , it have the same drawbacks to live with as before.

If i want is no big deal to turn down the settings ( save P3D profile ) and disable SLI as i did with the 1080TI ,to run TDFI, AS A320 , and XP11 ( dont support SLI as P3D do )for example.

1200$ can do 4k stuff while 300$ can't get you anywhere! well that was obvious !! Fact is , Clouds are not all GPU dependent, as LM Staff stated in LM Forum Clouds are processed by both the CPU and GPU and the load on each of them depends on the distance to the cloud!

This is because of the cloud morphing options in the automation window. It’s expands the size of the clouds to add realism, the up-shot, lower FPS. Disable 3D cloud morphing and cirrus morphing. This will help. FYI make sure the 3D clouds are rest back to .50 in the manual tweaking mode after doing the above.
