helios123 Posted October 26, 2015 Report Share Posted October 26, 2015 hi i have 980 ti on 4k monitor. it seems skymax pro 3 is soaking up more vram than pro 2. already 1.5gb past the 6gb on my 980 ti even with pretty low settings. Do you guys need to make more optimisation or something? Quote Link to comment Share on other sites More sharing options...
veeone Posted October 26, 2015 Report Share Posted October 26, 2015 I concur! I have a new NVidia 980, 4Gb VRAM. I am seeing just 128 MB free after reducing the settings to minimum. By that I mean every slider left and effects off? Something is not correct here? Quote Link to comment Share on other sites More sharing options...
sundog Posted October 26, 2015 Report Share Posted October 26, 2015 SkyMaxx Pro 3 actually uses less VRAM than SkyMaxx Pro 2 (unless you've cranked up the cloud draw distance setting, of course.) Something else is consuming your memory. Quote Link to comment Share on other sites More sharing options...
Nano Posted October 26, 2015 Report Share Posted October 26, 2015 (edited) I have to agree. My system is down to a crawl even on "normal" resolution. I'm seeing f-act below 1 and have to force quit the XP to get my system back. Might have to do with 10.41. I'm stepping back the 10.36 to see if that makes a difference.

Cameron Posted October 26, 2015 Report Share Posted October 26, 2015 Aside from the original poster, what are your monitor setups? Quote Link to comment Share on other sites More sharing options...
dpny Posted October 26, 2015 Report Share Posted October 26, 2015 FWIW, I saw this running 1080 with SMP 3.0: about 60 MB of VRAM left on my 980. Could be cloud draw distance, which would be a shame, as that's 3.0's best new feature, IMO. Quote Link to comment Share on other sites More sharing options...
veeone Posted October 26, 2015 Report Share Posted October 26, 2015 My monitor is single Dell Ultra Sharp 2560 x 1440. Set up in XP rendering as ;- Compress texturestexture res Highframe rate lock to monitor, as refresh rate of monitorrun at full screenscreen resolution Default Monitor Settings I have reduced my XP rendering settings down to where I see a texture load of 1227Mb (used).

This resulted in, I got the Skymax down to 752 MB free? (which jumps about, +- 50, BTW!)However, what I don't understand is if we have 4000 (4Gb on a NVidia 980) VRAM, then 4000 - 1227 = 2773? (Available)Where does Skymaxx get the number 752 (Available) from? So far with a short flight over w2xp Europe in the FJ Sim 737, I am stable at about 30 fps. Weather downloaded by FSGRW and the clouds look amazing! I have herd some can run ok with 200 Mb VRAM available, but I just wonder where Skymaxx is obtaining its VRAM number from? I will fly some more and hope XP hold up. Regards David Quote Link to comment Share on other sites More sharing options...

(Available)Where does Skymaxx get the number 752 (Available) from? X-Plane's VRAM numbers in the rendering window are NOTHING to go by. SkyMaxx Pro actually does API calls TO your video card to get true numbers. Rendering settings numbers are essentially junk, so what SMP 3 says you have...is what you have.

sundog Posted October 26, 2015 Report Share Posted October 26, 2015 SkyMaxx Pro reports the actual amount of free VRAM your video driver says the card has available to it. There are many things other than textures that consume VRAM, for example the video buffers needed for X-Plane to draw the scene. If you're using HDR mode on a 4K monitor, that's likely to be the biggest consumer of VRAM. Quote Link to comment Share on other sites More sharing options...
Jose Almeida Posted October 26, 2015 Report Share Posted October 26, 2015 I would add that other apps running concurrently may also use VRAM, thus reducing the amount available. Just my 2 cents. Quote Link to comment Share on other sites More sharing options...
helios123 Posted October 27, 2015 Author Report Share Posted October 27, 2015 when i go to rendering options in x plane 10 it says all loaded textures take up 2.5gb, but my vram consumed is 7gb... is there anyway way to temporarily disable skymax pro to see how much vram it is really consuming?

sundog Posted October 27, 2015 Report Share Posted October 27, 2015 Like we're trying to explain, there are lots of things other than textures (and SkyMaxx Pro) that consume video memory, especially when you're running at high resolutions with HDR on. But to answer your question directly, you can disable the "SilverLining" plugin from the plugin admin menu to temporarily disable SMP for testing purposes. You could also just fly in a scene with clear skies as a test. Quote Link to comment Share on other sites More sharing options...
arb65912 Posted October 30, 2015 Report Share Posted October 30, 2015 I have read many reports about X-Plane misbehaving in different ways and I can not resist the feeling that most of these problems were reported after version 10.40.I do not think SkymaxPro has anything to do with it.Last night I installed one of these monitors for GPU RAM usage and I got some very interesting result.I was flying 3 payware aircraft for more than 4 hours.What I observed was the constant increase in my available 3 GB or GPU RAM when it was only couple hundred MB left but the frame rate was great in 40+ range.I can not resist the feeling that the XP 10.40 is the case here.What are your thoughts?

Ayki Posted December 6, 2015 Report Share Posted December 6, 2015 (edited) Sorry for the late replay. I wanted to write this for future post readers like me. NOTE: I am a Win10-PC user.Always check your hardware from drivers, for example do not take xplane data as reference (skymax 3.0 show correct ram amounts as stated).According to my limit tests for my hardware skymaxx show same amount of available ram with MSI Afterburner and EVGA Precision. Also if you see "NOT RESPONDING" on the title do not shut down immediately, wait a little and let system to do what it is doing. TL DR; use MSI Afterburner or EVGA Precision for VRAM, use HWinfo for System Ram and CPU usage (Task manager is also ok).Edit: My system for xplane is 3770@4.2, 16gb ram, 980GTX (oc), 850 pro ssd Edited December 17, 2015 by Ayki Quote Link to comment Share on other sites More sharing options...
ckZA Posted December 7, 2015 Report Share Posted December 7, 2015 (edited) To no one in general: Disable SMP3, crank cloud detail up to 40% and see the performance then. I've had zero issues with SMP3 looking at performance. It's been better in most cases. World2XPOrthoHD MeshComplex airportsHigh settingsIncorrect NVidia settings...That's where you take the hit. If you think that because I got xGb Vram and I can work my way towards the limit, you are in for a bumpy ride. If XPX tells you it's using 1GB, you can be sure that real usage is 2x or more. When VRAM is full, you will slow down while old ram is loaded out and new ones are loaded in. While your PC is running, XPX is not the only thing consuming VRAM too. I set my sim up with the following steps looking at performance at each step:1.) XPX with standard world scenery2.) HD MESH3.) NV settings4.) Airports (aka non library dependent airports)5.) Adjust ingame settings5.) SMP3.0 plus weather injector6.) Word2XP and Orthophoto.7.) Adjust ingame settings. I've attached three screenshots from KSFO - no World2XP. I'm running a 4GB orthophoto tile with custom 3.2 million triangle mesh, SMP3.0 and Skymax Audio. 4.6GB VRAM use. Notice my in game settings - I don't want more than 4.5GB VRAM use and I'm edging over it even though there's 6GB. Edit: I run 1440p resolution even though I have a 4K monitor. If XPX supported SLi, two 980Ti' might come close to rendering 4k and high levels of intensity (Mesh / Ortho / W2XP). We're still some time away from 4K performance on a single GPU. In game with all the above If I disable SMP3.0, go up to 40% clouds I drop 100mb in VRAM and the FPS goes down 10fps.

FloB Posted December 8, 2015 Report Share Posted December 8, 2015 After a lot of trial and error-testing and some reading up on vram the whole matter seems to me a very, very complex one. Laminar advises users to set their rendering settings so the size of loaded textures is about the size of the vram on the card (http://www.x-plane.com/?article=setting-the-rendering-options-for-best-performance). That means the total ram demanded by the driver will be much higher. And actually I found that sometimes I can run just fine (stable 30 FPS) with a vdrivers' ram usage that is much higher than the vram on my card (3.5GB / 4GB, GTX 970).Obviously not all the stuff that the driver loads is needed to be kept in the card's vram to maintain performance. Some might sit on the "slower" system ram without harm. (This is part of the explanation that NVIDIA gave for it's 3.5 GB (fast) + 0.5 GB (slower) vram-design on the GTX 970). So while it is mandatory not to exceed the card's vram in terms of loaded textures this is not true for the total ram usage of the driver. That means you actually have to test different resolutions in order to find the sweet spot. Don't go by the numbers, neither those of the total texture size that x-plane reports, nor by those the driver reports.Check the real FPS/frametimes instead and see what difference the different textures resolution make (don't forget to restart the sim!).At least this is the bottom line for me.
