Terrain loading under P3DV4.2

Recommended Posts

Hi everyone,

Just a small observation which might have bin covered.

I notice a increase of sharpening textures in the distance using high resolutions textures and TEXT_BAND_MULT=80

The differentcies is the distance that texture was loaded including photoreal (ORBX LOWI)

Can anyone explain this ?. Seems that my SLI 970 can keeep up quite a bit

Why is High resolution texture also improving distance  photoreal loading ?

Thanks

Michael Moe

Hi Michael-

Poppet explained this either over at LM or here. If I recall, higher res textures are loaded initially in the LOD 'ring', depending on your setting. So, it's not a 'photoreal loading' thing, it's and 'already loaded' thing. If you search this you'll find it.

Cheers,

Mark

Thank you , my first concern with only 4GB VRAM then. I need a new GPU

 

Thanks

You can increase this even more with TEXTURE_SIZE_EXP set to 9 or 10(default is 8 when no entry exist in CFG). But to use it, you need at least 6GB VRAM for TSE=9 and at least 8GB Vram for TSE=10. Also, for TSE=10 you need more then 8GB RAM. I have 1060 6GB Vram GPU and only 8GB system RAM. Using TSE 9 it's not a problem, but i tried with 10 and P3D couldn't be loaded, i watched my RAM usagge increasing to full and my PC freezing.

BTW, i have no performance impact by increasing it to 9, only higher Vram usagge

Plus, you need time. While TEXTURE_SIZE_EXP= 9 is bearable yet, TEXTURE_SIZE_EXP=10 makes loading time unaccaptable(>5 min). Thus, I decided to settle with 9, for now.

You may compare this to AeroflyFS2 using photo scenery (+ autogen) as well, starting up within 15s and rendering sharp until the horizon. So it can be done.

Kind regards, Michael

Edited for clarity:

Adding TEXTURE_SIZE_EXP= 9 in Prepar3D.cfg,  if "Use High Resolution Terrain Textures" is already checked in P3D, has no effect.  (Nor does it do any harm..)   :cool: 

Just do not use the combination:

"Use High Resolution Terrain Textures" unchecked in P3D, and  then adding TEXTURE_SIZE_EXP= 9 in Prepar3D.cfg,   as documented below.

 From LM - 

For default 256:
HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=8 (or not set)

For 512:
HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=9 (or not set)

For 1024:
HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=10

Please do not use these setting combinations as they may cause problems:

HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=9

HIGH_RESOLUTION_TERRAIN_TEXTURES=0
TEXTURE_SIZE_EXP=10

HIGH_RESOLUTION_TERRAIN_TEXTURES=1
TEXTURE_SIZE_EXP=8

Thanks. Sadly the last combo would have bin nice om my low VRAM system.

TEXTURE_SIZE_EXP only applies to LC, PR is still capped ... hopefully that changes in the future but as I understand it there are some tricky complexities and issues around maintaining compatibility with existing content (the ball and chain).

LC, PR? What are those acronyms?

I must be having a senior moment since I am usually good with acronyms.

Many thanks,

I'm guessing LandClass and PhotoReal, as in textures 🙂

Kind regards
