dlrk Posted January 28, 2021 Report Posted January 28, 2021 Strange, but hopefully reproduceable issue. When I start descent from a cruise altitude, FPS drops to 19-20 and stuttery around ~25-26k feet. Changing the cloud draw distance (lowering or increasing) resolves this, and the FPS resumes a normal frame rate. Quote
sundog Posted January 28, 2021 Report Posted January 28, 2021 My guess is that memory was getting tight... when you change that setting, it causes all of the clouds to get deleted and recreated, which might alleviate memory fragmentation issues that may have been building up. You might have to pull back a bit on your cloud draw area setting. Quote
dlrk Posted January 30, 2021 Author Report Posted January 30, 2021 This issue seems to be resolved, the frames still drop, but briefly and recover without me doing anything. Not sure if it's from lowering the draw distance or the 5.0.6 update Quote
dlrk Posted January 30, 2021 Author Report Posted January 30, 2021 Never mind, occurred on final. It doesn't look it's memory, unless it's VRAM getting filled. But I have 8gb Quote

But I have 8gb VRAM would be the issue here, if it is memory related. 8GB fills up fast, especially at high resolutions and/or with custom scenery installed. Quote
dlrk Posted January 31, 2021 Author Report Posted January 31, 2021 I'll check for that next time, thank you. Sounds like it's thrashing memory when it gets full. If this is the issue, is it possible to lower SMP cloud res? Quote

If this is the issue, is it possible to lower SMP cloud res? The volumetric clouds will consume less memory if you lower SMP's cloud draw area setting. Or, you can select something other than volumetric for the cumulus and/or overcast representation; the non-volumetric clouds use less memory. 1 Quote
dlrk Posted February 13, 2021 Author Report Posted February 13, 2021 So, upon experimenting with this for a bit and checking VRAM usage with GPU-Z, this is not caused by memory filling up. There appears to be no correlation between VRAM usage and FPS. FPS is limited by CPU frame time when this occurs Quote

sundog Posted February 17, 2021 Report Posted February 17, 2021 Assuming you were using the new volumetric clouds, try lowering your anti-aliasing settings. Maybe that will free up enough performance overhead to help. Quote
BiltongBoer Posted February 17, 2021 Report Posted February 17, 2021 I am having the exact same issue with an RTX 2070 8GB. AA already set to very low. The cloud draws just kills it completely for a few seconds and kind of kills the realism in the sim, which is unfortunate. Would love to help anyway I can to get this sorted, as SKymaxx pro 5 has a lot of potential! 1 Quote
BiltongBoer Posted February 17, 2021 Report Posted February 17, 2021 Also, and apologies if I'm reinventing the wheel here!! BUT, is there a recommended config for the RTX 2070 8GB's that I can test out? As stated above, I have pretty much put all other settings on low, which is kind of defeating the object of why I bought this card. Quote
dlrk Posted February 18, 2021 Author Report Posted February 18, 2021 Yeah, I have that same card. I wonder if the a 2070 just isn't powerful enough for the volumetric clouds? 1 Quote
BiltongBoer Posted February 18, 2021 Report Posted February 18, 2021 Hi Dirk, I realised something last night. I'm running a UHD monitor and have XP on the UHD resolution. When I brought it back down to 1920x1080 the hit was much smaller. Given we don't want to go on lower settings - that's why we pay the money for the rigs, right, I'm going to test today/tomorrow on the HD settings as opposed to the UHD and see if that makes a difference. Quote
dlrk Posted February 18, 2021 Author Report Posted February 18, 2021 I'm at 2560x1440, not sure if that is UHD or if UHD is 4k Quote
BiltongBoer Posted February 18, 2021 Report Posted February 18, 2021 I was running at 3840 × 2160. Might try 2560x1440 but if you struggled with that, I'm sure i will too. Testing it now and if anything it is still the same if not worse. Very sorry now that I spend the money on Skymaxx pro instead of Xenviro...Will make sure I advise accordingly Unless somebody from skymaxx care to assist here of course, i.e. with advice etc., but it's been really difficult getting assistance...

BiltongBoer Posted February 18, 2021 Report Posted February 18, 2021 Ok found the culprit....stay far away from volumetric anything in skymaxx pro!! Choose Fast clouds, looks awesome and performs brilliantly!! Quote
