LOD in LOMAC

[TBT_Piper]

I am wondering since I get a hit of FPS when many objects are out of view what kind of LOD do the models have in Lock On. How many LOD's are there? And how many polygons are in the models when they are very far away.

 

Any help would relieve my Paranoia. :rolleyes:

It depends on the models in question. It is true that some of them have only the main LOD, with no "ligher" substitutes. But that is not the norm. In case you missed it, the LOD Objects Fix that was recently released adds a very simple 'box' model for most ground vehicles when viewed from more than 1 km away. Most aircraft have more than two LODs (three?). I believe we can still expect further improvements in the future, though I'm only speculating now.

 

To check the number of polys on the screen, hit Ctrl+Backspace twice. Look for the variable TRG (or something like that, stands for triangle). If the object in view has multiple LODs, that number will lower as you zoom out and vice versa. Note, to do this with any degree of accuracy, it is best to view a single object against the sky as background.

Some models have no LODs at all. The f-18 model is the same at 5m or 5km so even if you only see a pixel the cpu is calculating the entire geometry.:rolleyes:

Sounds "Uber" wasteful of CPU management. Maybe 1.2 will incorporate some more LOD's :)

This is very interesting. Is this at least one of the factors at the heart of why LOMAC is so CPU intensive? I've heard the term LOD but could someone define it for me?

 

I noticed that simplying slewing my in-cockpit view around can cause a huge difference in frame rates . . .especially when I'm headed for the AO. I'm assuming this frame rate slow down is because one view is trying to render huge tank battles (ie, a bunch of objects) that are completely beyond my view. If so, this is clearly an inefficient use of CPU horsepower. Is this what the mod is working to correct?

 

Is this mod available for 1.02? Or, if this idea is tracking, is there a .cfg or .lua or a .something file that this mod tweeked . . . that we can get into and tweek ourselves? I see that the mod is an .exe file. Has anyone cracked it open to see what's in there. By the way, how do you crack open an .exe file. Darn, I should have numbered these questions!

 

I think a big Vcard won't solve this one. Is this the basic CPU, "not enough horsepower" issue. Might this be a direction to continue that might help the game run more smoothly?

[TBT_Piper]

The Mod is only for FC. :(

 

As to what the readme file says this helps by making the objects less polygons after 1 Km of distance. So the Ground Units would go from say 400 polygons to 4 once it reaches 1 Km.

 

Now on a larger scale this is great because if you have 50 ground units then that could be 20,000 poly or 200. :)

 

I think the Dev's should add at least 3 LOD's to all models which is possible.

 

Sorry for drawn out post but meh.

Keep in mind that not only models are calculated any given time. Missiles, radar, AI, flight models, etc are calculated too. So an air defense site may be farther that 1km and thus only rendered as a cube but it's radar is tracking you, it's AI is working to shoot you down, etc.

But something is indeed wrong when parked at base you get 10FPS just by looking at some other aircraft or buildings and 45FPS when looking inother direction (or 150FPS when looking at the sky).

I received an email from Chizh and Igor Tishin half a year ago, and they confirmed that FC contains LOD's for the F/A-18.

Really!!

I didn't know that, sorry for the misinformation. :icon_redf
