Yes, ok, I know, I will able to check this out myself coming monday but it's fun talking about all this so hence this topic anyway.  ^_^

 

In FSX I use one tweak: Bufferpools at zero. This tweak makes a world of difference on my PC. Enabling it makes it seem I put 1000 dollars of new hardware in my rig. I have read that none of the FSX tweaks seem to work in P3D 2.0.

 

Now I am wondering how many beta testers were also using the BP tweak in FSX. The thing is: if they didn't use that tweak the difference between their FSX and P3D may seem great but I fear the difference between MY FSX with the BP-tweak and P3D may be not so great… or even disappointing. If you know what I mean.

 

I gave one of the first P3D version a try with that one month free option you had back then and without any tweaks it ran TERRIBLE compared to my BP-FSX, while a lot of people said P3D ran great… but those people weren't using the BP-tweak in FSX.

 

Well, anyway, I am a bit afraid that P3D 2.0 without that BP tweak won't run as good as FSX does with the BP tweak. Maybe a beta tester who did use the BP tweak can share some experiences on this. Again, I know I will be able to check it all myself as soon as I have P3D 2.0 on my PC but I am just curious…  -_-

I think p3d will take full advantage of your gpu, so hope you don't need anymore BP in p3d.cfg.

 

My big hope is you have not to touch in anyway p3d.cfg, like in xplane.

I think it's a valid concern.   Even with the BP=0 tweak in both FSX and P3D 1.4, I too got dramatically better performance from FSX.  I just never saw any of this "P3D is just natively more smooth" business.   Maybe that's because I use ATI GPU hardware...... maybe not.

 

 

  In like for like FPS comparisons using the Aerosoft Airbus X Extended at FlyTampa Athens, I got 28 FPS in FSX and 23 FPS in P3D.     That was with broadly the same settings (FSX LOD increased to match P3D's native), and with just HIGHMEMFIX and BP=0 tweaks in the CFGs.

 

The question is, will P3D natively have a more optimized or better BP configuration.   If that's so, then the lack of ability to use the tweak may not matter.

 

A lot of questions will be answered on Monday.   :smile:

Hm… when I read your replies it suddenly hit me that the BP-tweak simply is a tweak that makes your GPU do more of the hard work… and P3D 2.0 is ALL about letting the GPU work harder… so you could indeed say that P3D 2.0 has the BP-tweak built in. Sort of. Not literally, of course. Anyway, I think I will sleep better now so thanks for setting me on the right track!  ^_^

Well, I don't use the Usepools=0 tweak. It caused too many spikes and texture flashes, and CTDs in some busy areas, so I won't miss it.  

 

Hopefully we'll never have to touch a cfg file ever again.

I get the odd flash, but not many (and greatly reduced by changing the [Display] TextureMaxLoad value to 18).

 

A worthy comprimise to get a 10-12 FPS boost, which is what I see with BP=0 active.

I'm guessing my CTDs (when using Usepools=0) are cause by my extremely dense autogen settings, and my GTX580 running out of RAM, so I prefer to set my pools manually. Will try it in combo with the MaxTextureLoad tweak and see how it goes.

That would be a great disappointment for me!!!

 Very possibly, as I have always used "Normal" setting for Autogen, regardless of my hardware.  I just prefer that level as it's just the right amount of autogen, without noticing excessive 'popping' all of the time IMHO.

I'm hoplessly hooked on autogen, especially on trees when flying low and slow with the Piper Cub or Helicopters. I set the amount of trees to 6000 in the cfg for wilderness areas, but reduce to 1000-1500 when flying over cities.

Completely new engine. It might not even use any buffer pools in the first place. Surely most old tweaks will no longer work, and many new ones will be discovered over time.

Don't want to turn this into an FSX tweaking topic LOL but I also have an GTX580 and also have autogen at Extremely dense (though at the defaults settings so not at 6000 trees) and I never ever have CTD's and only one or two spikes/texture flashes during a flight. Maybe this also has to do with the CPU one uses? I have an i5 2500K @ 4.5 GHz.

 

Anyway, I also really hope we don't need any tweaks anymore. But… the fact don't old tweaks don't work anymore doesn't mean there aren't any possible new tweaks…!!! :rolleyes: We already know P3D will ask a lot of our hardware so not many people will be able to fly with 'all sliders right' and so it wouldn't surprise me at all if some (or a lot of) people start digging in the new cfg's for new possibilities…  ^_^ I don't like tweaking but if I know it's possible to get P3D running better at no extra costs, I'd be a nut not to do it!!! 

 

EDIT

Indeed!  ^_^

They (P3D Devs) have said in their forums that many enhancements have been done to increase performance. Lets not forget the CPU is used in FSX to calculate a lot of the rendering functions, now imagine that all of this is handled by the GFX card via D3D11. That frees up the CPU to do more important tasks and I would also imagine maybe some new tasks. Dividing up those tasks to multiple cores should be easier now too.

LM has not really commented on every FSX tweak, but my understanding is that most, and I say most, have been removed based on other forum posts I have read. From a stability standpoint, I would guess that after all of this work to rewrite the graphics engine that it would not be beneficial for most of the tweaks to even be looked at when p3d loads, at least those tweaks that use the BP keyword and other memory type keywords. I say this because these types of tweaks are directly related to how the engine manages memory and would be in direct conflict with the new graphics engine. I do use the BP=0 tweak and have been using it from day one and never looked back, but I cannot for the life of me believe these cfg entries are even looked at anymore when p3d loads.

Me too, but what's the correct type in FSX.CFG:

 

Usepool=0 or Bufferpool=0?
