high texture setting load 100% VRAM

[JesterIsDead]

I have been tweaking my VR for the last week and noticed that my RTX3060ti is using 100% of the VRAM all the time. I tend to set graphics as high as I can tolerate low frames. After reading a few post about high texture setting, I bumped mine down to medium and that gave me some VRAM to play with. I can even set my SS in OTT to 1.2. I can't tell if the texture is degraded. Everything looks great, runs smooth even in Syria with terrain texture set to high and I am skimming the tree tops. This is in MT and ST settings.

Anyone know what the texture setting does to the VRAM?

Yes, textures -> medium and terrain textures -> low. When you saturate vram with quest 2 (my case), it's start with weired artifacts

High texture setting will take about twice the amount you currently have. That's what it does to VRAM.

[diego999]

The higher the setting the more VRAM usage.

I can't honestly tell higher from medium textures in my Quest 2. I guess with a better set the difference should be visible.

VRAM usage is the main problem for most people, I believe more painful  than the benefits ot MT.

For.VR I believe MT adds little to nothing to most people (my system 13600k and 3080 runs better in ST) unless you are running either an old CPU or a 4090

I mentioned this in another thread looong time ago and looks like nothing has changed.  In fact, has gotten worse it seems.  I optimize most of the textures.  Below is comparison between my optimized textures and default.  VRAM usage is at bottom right corner.  There is absolutely zero image quality difference.  Different shade of glass tint is just my personal preference.

As you can see, newer the module, bigger benefit there are from optimization.  I don't have Apache but its textures look huge.

All I did to optimize is reduce all RoughMet and Normal maps from 4K to 2K.  No change to Diffuse maps.  And converted ALL 32pc textures to 8bpc.  And all FLIR textures, I downsized to 1K.  Have no idea why something you see in small MFD screen needs to have 4K textures.

I thought about releasing this optimization as a mod but it's too large and it depends on the module.  I don't have all the modules.  But it's fairly easy to do if you download the MS Visual Studio Community which is free.

But then it wont pass IC so we only have to hope ED listens.

Taz, this is awesome, like the rest of your work. We do enjoy and appreciate all your mods.

Can you please give us more details about how to do this? Most of us have no experience with MS Visual Studio.

These optimizations should be a top priority for ED. For most of us these would be better than MT.

Does this apply to the IT23 in BS3? As soon as I turn it on I lose 2ms on 1024 resolution, A10C I lose almost nothing from turning the TGP on.  I do use your A10C reduced bit depth bump maps but I don't think that modifies the MFD display does it?

Making the IT23 as performant as the A10C TGP would be awesome.

Would it be possible for you to put together a quick and dirty guide on how people can modify the textures themselves?  I'm not too bothered about IC currently but if it can be shown to improve performance significantly on specific modules then it might help sway ED's hand to optimise (assuming it's not already planned and just waiting on resources)

I am referring to texture size, not in-game setting.

I made a short guide here

I know you were referring to the texture size rather than resolution, at lower resolutions the hit is less (on the IT23) but it is always considerably more (~2ms@1024) than the TGP on the A10C (~0.5ms@1024).  On 256 resolution the IT23 is still close to 1.5ms hit sometimes, it's also somewhat difficult to use!
I'll have a read through thanks

I see.  BS3 is still in development and I believe Shkval being in color is listed as a known issue?  So that may also have something to do with it.

[edmuss]

This is an existing issue that came in with 2.8 and the BS2 cockpit retexture/lighting overhaul, the performance of the IT23 is about the same between the colourised and the greenscreen version

Is BS3 still a developement module?  Being based on the most mature of any of the DCS modules I would have expected it to be fair well sorted, that is of course not to say that it's not lacking optimisation.

I'll have a play at creating an optimised KA50 and see if I can improve performance any.
