Cloud Type Killing FPS
« on: July 16, 2021, 12:57:56 AM »
So This issue of unplayable framerates in FSO and scenarios came up the beginning of the year, previous post https://bbs.hitechcreations.com/smf/index.php/topic,402601.0.html. I pulled my hair out for a few months trying to figure it out then it just disappeared. Well last Friday during FSO terrible framerates came back.

I set up an offline cloud test and found '10 Cumulus Mediocris' is the culprit. Using any other cloud type FPS was between 50-90 depending on type and where I was in relation (flying inside them usually gave me worst FPS) but all were playable. #10 dropped it to 0-3FPS if I looked in certain directions, just like during FSO. I've already asked the FSO CM if he can avoid this cloud type. Just wondering if anyone has had similar issues and knows a fix?

I tested using a small map I built a couple years ago. In ahclds I created a single front that covered most of the map, selected the first cloud type on the list, saved weather, opened ahedit and hit build. Then I launched the map in offline practice and took a Spit XVI to fly around the clouds, then closed AH and repeated with the next cloud type on the list. I used fpsVR to check my FPS and GPU/CPU usage. All in game graphics settings were turned down/off except for aircraft skins. Only change between tests was the cloud type.

my system :
HP Reverb G2
AMD Ryzen 5 5600X
AMD Radeon RX 5700 XT
32GB Ram

TL;DR '10 Cumulus Mediocris' cloud type destroyed my FPS in FSO last Friday. Anyone else notice issues?

Just out of curiosity: Are you using drivers you've downloaded from AMD or are they provided by Windows?

Other than that, how often do you give your computer a fresh boot? Like by keeping the Shift button down while clicking Shutdown?

If neither of those doesn't change your test results it really can be something in the cloud.

I've got an older system by today's standards that still runs the game well by my standards.

I'm using the drivers right from AMD, and the Radeon software to manage the GPU settings. I make sure to remove the old version of the driver when I update, ran into issues before with not doing that.

I don't do that complete shutdown that often, usually just the plain start-shutdown. I'll give that a try and retest, thanks for the suggestion!

The FSO cm last week was able to use a different weather file than he did the week before and this issue didn't come up.

I have a reverb G2 which is 2160x2160 per eye, close to 4k.
