DA62 VRAM Usage? Spikes to MAX....?

Recommended Posts

I have to say this plane is fantastic but my GPU Vram is spiking in default location with base textures to almost 4GB.  I do not have global+vector+openlc installed - just Orbx SoCal for testing purposes - but VRAM is pretty much maxed out.  I have tried No Mimap VC and Mimap VC (with the texture change via the app).  

Just not understanding why the VRAM is spiked up fully in default P3D flight location.  Heck even my lod and draw settings are dialed down quite a bit for VR settings.  

I need some free VRAM even the GPU Usage is spiking almost to 100% (I can hear the fans out loud) as this plane is amazing in VR.

Using 980 GTX here

@Sean Moloney? any ideas?

Even deleted my Prepar3d.cfg and tested it out with default one which the sim creates

Here are the screenshots and ultra low settings.  This much GPU usage shouldn't be used...something is wrong here? is it my installation? I did get my windows updated to 1809 (got forced into the update...like yesterday).

Any ideas on what is going on?

 

Thanks

I would expect two things are taking a lot of vram - you're running it at 4K and the texture resolution.

Yeah...I kinda got it figured out....it is the 4096 Textures....I am using no-mipmap and set the scenery textures to 1024.  Still takes lot of VRAM, and in desktop mode - Vsync needs to be on as the gpu shoots through the roof.  I don't know what windows 10 1809 is doing.  But for VR - Vsync needs to be off, I just boot p3d in VR mode straight.

Yah, I need to get 8gb+ new video card soon.  But I got it working and my shaders some how got messed up with EnvShade, it made the gpu spike like crazy...something is not right with it - especially for p3d 4.4.

 

Anyway - this plane needs to be seen in VR - omg it feels so real....the cockpit is so realistic omg....so many buttons, I have no idea what they all do.  Manual reading is a must.

Hi Lenny777 !

I have the some VRAM and performance problem too. I have only 4GB Nvidia Gf 1050Ti card (and an old i5 750/3500 MHz 8Gb/1600MHz  RAM system), and this plane unusable for me at this time and uninstalled now. This plane perform worse from my addons. Worse then F1 B200 ( Surprisingly), Majestic Q400,and PMDG737NG which I can use without big problem with my outdated system with internal locked 20Fps. My GPU load 100% with this addon and I have a lot of microstutters, and with my F1 B200 with similar G1000 I have only 25-30% VRAM load. Reduced all sliders a lot but it's not helped too. Internal sound is gradually changing (Steep with 1%) with the engine speed changes and not continuously fluid as in the external sound. Updated the GPU drivers too. I'm very disappointed because I didn't read minimal system requirement before  I bought it because the AVSIM  Membership reported good performane with this nice addon. I have fresh P3D v4.4 and with only several planes installed now, no OrbX or other framerate killer apps installed so far.

Sorry for my bad english, not my native language .

I have a 1080 ZOTAC 8GB. GPU running about 45% in the air. I have all the ORBX stuff including Germany (where I'm currently flying) and running 4XSSAA with texture res at 2048x2048. If you look at the config Vertx app you might want to disable several of the graphics settings including reflections. But the textures are beautiful in the plane so yes it does tend to hit your fps. I had the plane in a hangar at EDDN (payware) with 8XSSAA and it virtually brought the plane to a halt. Around  5 fps so unflyable. I changed to 4XMSAA and turned FXAA on it was much better went back to twenties. But yeah, depends on how much you tax everything.

I have the same issue here, running in 2D. GPU temps are on the high side, but still pretty safe.

High res textures and 4k on that video card is pretty much the cause.

Vertex designed the Aircraft for P3D only(As it should be 😊) and accordingly it is using your GPU for many things, I imagine even gauges displays are being rendered by the GPU 😉.

You are hitting hardware limitations.

I'm looking in to this. There's plenty of scope to compress the textures - it would be a shame because it would lead to reduced texture quality but worth it of course if it fixes this problem. I am a little surprised, it's not something that was causing trouble during beta testing.

I'll be releasing an update in the next few weeks with a few minor fixes and a few new features.

I did not notice these spikes or heating with my old GTX 970 FE & my 1080P monitor.

I have upgraded to a 1070, but even that might not be enough for 4K since I also want the best visuals that I can get.

I think we all need to check our shader presets, because even changing shadow settings with PTA can have a dramatic impact on fps.

I tend to think that some of these problems being noted may have more to do with shader utilities like Tomato Shade, PTA and EnvShade and not the aircraft. Those three shader tweakers were released quickly after the 4.4 update and might not have been checked as carefully as possible. PTA still has a problem with one of its water settings.

Maybe someone else can answer this. Like the RealAir TD, some of the additional sounds in this aircraft are handled by Doug Dawson's sound gauge. I can't recall offhand but does the P3d UI muting function also impact the custom sounds in the Duke? I'll have to check myself.

Doug Dawson says: Yes, but you need his latest sound gauge version.. just read this forum.

What happens if you reduce global texture size to 1024 or 2048?

Okay, the Vsync situation is solved - GPU utlization has stablized after clean install of P3d.  EnvShade did mess some things up as mentioned earlier (it says it is compatible with 4.4 but I can't even see any difference - something is wrong with it).

 

The textures on this airplane are in a league of its own.  @Sean Moloney the quality is amazing.  Guys once you see these textures, it is hard to go back to anything else.  This truly a new plane for 64bit world.....I do have to get a 8GB video card anyway, so no biggie.

 

Sean did you undercharge all of us on this? this is a like a over $100+ addon - you just raised the bar on every aircraft developer especially at this price point.  Best Christmas Flight Sim addon for me 😊

 

What is interesting is that Vsync has to be On just to bring the GPU load down a bit - this interesting to see in P3D4.4 with this addon.  Envshade did 100% mess some shaders up and even restore didn't work properly - so that app is grounded.

The manual has amazing amount of graphics settings - really helped me get most of this bird.  Please don't scale the graphics down - holy $$$$ this is work of art.

Mimaps enabled one needs 4096 textures and that does take VRAM due to the extra textures being loaded (the manual said all those things, and I learned it properly for the first time....wow).  

I am able to bring VRam usuage down by scaling scenery textures to 1024 and loading No Mimaps in VC and installing the No-Mimap Textures.  I am down to 3.4 GB Vram on default location with some of the sliders to the left and doesn't bother me.  All is working as intended.

 

I found a unique installation bug and @Sean Moloney, I just emailed you with all the details to your address on the site

 

And for some reason the plane remembers my settings even with ready to fly option is enabled.  Is there way to have a setting to reset on what wrong buttons I have pressed.  I love the realism, but while I am testing it with my testing to get things squared away, I need to be able to load up normally without the remembering, that part comes in use once my Sim is stabilized for new VR settings

 

And this setting helps

[GRAPHICS]
ENABLE_MEMORY_OPTIMIZATION=1

 

Update:

Everyone - I got everything sorted (stayed up late fixing it)- Shaders got screwed up and even restore didn't function.  Had to clean install P3D again - GPU Utilization is normal even though VRAM is high but video cards can handle it (they have super fast bandwidth anyway).  Utilization spike was the crazy one - and be very careful with whatever shaders you install.  I have not using anything and don't intend after all the time waste Envshade did on my system.

Sean leave the textures as is, this is the future of Prepar3d 😋

 

Mods - can you update the thread to solved.  I do not want others to get a wrong impression.  I got the GPU spike solved, this thread should help others who could be facing this issue

Hi Bert

Better with those settings, but the internal engine sound lag terrible and it's useless to me. The VRAM load goes back to 3-4 GB, frame rate was acceptable now, but the sound issue is there. I've tried everything already (motherboard sound driver reinstall, sound quality settings back to 16bit/44000Hz CD, and Nvidia HD audio disabling, Latency check).  The engine/prop sound goes up and down very slow and laggy, compare to the external sound. And every change on the G1000 screens, while reloaded the data, cause framerate drops and sound lags. Every other addon works good (PMDG NGX, F1 B200, Majestic Q400, A2A, F1GTN). My system is poor for this addon I think. I was not patient enough with this purchase. I don't want purchase any hardware for my aged system, and my video card only 5 months old, because the preious card ruined. A complete new system too much for me now. Uninstalled again 😞

For future proofing, I'm not sure 8GB is going to be enough!

There is no such thing as Future Proofing.  The cards which come after 2XXX series will have 16gb to 24gb.  Things are always gonna improve

Lol and that will be occupied with ray tracing in the future 😉 So indeed nothing is future proof...
