What does "use High-Resolution terrain textures" affect?

Recommended Posts

I am confused about the use of this option. Does it affect the sharpness of the default ground texture, photoreal ground texture, or autogen texture?

It should affect any groundtexture but the effect is rather subtle. I myself can't really see a difference while flying and even on comparison screenshots I doubt if I see any difference. So I have it turned off. Don't know if that saves fps but is sure saved loading times.

Can' see a difference? Without it you see the LOD decreasing like it did in FSX and v3. If you turn it on the groundtextures become much sharper in the distance.

Ok, I will give it another try then. I only tested it from one position, taking screenshots, and not while actually flying... I understand the difference becomes noticable only while actual flying?

Remember that GPU memory is increased so you would need at least 6GB Videoram.

My GTX970 4GB cannot handle it

My GTX1080 shouldn't have any problems with it then. :happy:

It makes a huge difference, especially if you go back to v3 after flying in v4

Thank you guys so much! I asked this in the official forum but got no answer.

If it turns the ground textures in the distance sharper, is it the same as increasing "TEXTURE_SIZE_EXP=10"?

Should I just change one of them, or both?

9 Is what you will see setting the in sim "use high res textures"

10 is only settable via cfg as you need more than 8 gb VRAM, my 1080TI runs using 10GB VRAM consumed at this setting

My 1080Ti still runs ok using "10" in the .cfg performancewise, but it definitely increases the loading time beyond acceptable levels. As "9" is already a big step up compared to v3.4, I have it on "9" now inside the config and unchecked inside P3D, for me the best compromise in loading times and ground texture display.

Think of it like the "extended DSF" option in XP10.

I tried TEXTURE_SIZE_EXP=10 with my 8gb GTX1080, It can run, but I am not sure if it's too much for the 8gb card.

My 8 GB GTX 1070 basically choked on the 10 setting. I ended up running out of physical RAM (and getting an OOM of all things!) as I think it was trying to compensate for running out of VRAM. I'm now using 9 without any issues. It works great.

I have a 1080TI which has 12gb VRAM, this handles 10 no problem. My old 1070 couldnt handle 10 as it would run out of VRAM and FPS would drop through the floor

I have an 8gb GTX1080. When I set it to TEXTURE_SIZE_EXP=10, the ground texture further away seem to be a bit sharper, and there is no noticeable loss of FPS, but the loading time is much longer. I might stick with TEXTURE_SIZE_EXP=10.

Well, I gave it another try (the option from the settings menu which is 9 afaik). I set up a flight with a default plane on autopilot and running at 4x the speed. I let it fly for a minute and then took a screenshot. I did this with and without the setting. And yes, there were subtle differences to be seen when I closely compared the screenshots. The textures further away were a bit more high res with the setting on. Not mind blowing much and I seriously doubt if I actually notice it during a regular flight (instead of comparing 2 screenshots) but it does make a slight difference. And since this doesn't seem to have an impact on performance I might as well use the setting. I do not think however this is one of THE best things of v4 as some say. It is way too subtle for that.

I agree BUT there are times, when breaking out of the clouds when I can see clearly to the horizon and it's sharp and crisp - they take my breath away. Reminds me of many time IRL when that would happen. In those moments, I would have to disagree with you.

I believe it's the overall flight experience(s) that people are commenting on - not just a single flight or screen cap or video.

That sums it up very well!

In my mind, there is not a single thing that makes P3DV4 better, but the sum of all the parts that produces a more convincing experience. 

I have not started up FSX in weeks now.. :cool:

Yes... When you buy a new sim you tend to focus too much on details while it is all about the bigger picture. I'll stop focusing on details immediately and simply enjoy my flights. :happy:

And THAT'S what it's all about. I did some hurricane hunting yesterday using ASP4/ASCA - talk about sweaty palms - it took me back quite a few years to some similar RL situations. 

P3D is not perfect - far from it - but the plusses WAY overshadow the minuses, especially if you don't focus on them.

It's like having a dead pixel in your TV or monitor - one pixel doesn't really make any difference at all EXCEPT for the fact that you know it's there and it bugs you.

Enjoy -

I switched on and off "use High-Resolution terrain textures", and the difference is minimal. I compare TEXTURE_SIZE_EXP=10 and 9, and the difference is minimal, but the difference in loading time is huge. So I just turn it off, and changed TEXTURE_SIZE_EXP back to 9. Still wish LM could allow us to increase lod-radius to bigger than 6.5. In the old FSX this is something that really helps.

You are aware about the fact that "default" is NOT TEXTURE_SIZE_EXP=9 but no entry like this inside the prepar3d.cfg? So, if you want to do a proper comparison, you have to compare the visual appearance of P3D once without any texture_size_exp tweak and LOD 6.5 vs your 9er setting. Otherwise it is apples vs. pears...

In FSX, when I set LOD_RADIUS to 12, all the blurries, far and near, are gone.

In P3D, the difference between TEXTURE_SIZE_EXP=8, 9, 10, or no such line, is minimal.

It's not apple and orange.

You do not get the point. If you want to see what this TEXTURE_SIZE_EXP line really does, you have to uncheck the tick at "use high-resolution textures" AND remove the line from your config. Then you see how P3Dv4 looks like with the simple LOD 6.5 setting. If you use the tick at "use high-resolution textures", you basically have the same setup such as using TEXTURE_SIZE_EXP=9. So, you have to compare the basic LOD 6.5 setting to EITHER "use high-resolution textures" OR TEXTURE_SIZE_EXP=9. Comparing other stuff does not make sense. Certainly not, if you compare TEXTURE_SIZE_EXP=8, 9 and 10 while having the tick constantly set at "use high-resolution textures"...
