[BufferPools] PoolSize=0 the holy grail of FSX performance...

Featured Replies

I'm using 5870 with vsync forced through ati tray tools. i'm seeing awesome framerates with bp=0. i often have solid 60 fps (rural areas). i think it's a good card for fsx.

I am beginning to lose what the objective of this tweak is all about, and maybe need reminding ! I have followed this topic with avid interest as I too want FSX nirvana and am willing to try most suggestions. My initial understanding was that the advised BufferPool setting of zero produced for some, a completely SMOOTH flight (regardless of FPS although some saw improvements) and that smoothness was the goal. Tests were/are undertaken to see who could get the tweak to work and further tests to see who could get it to work with the highest settings. I for one, cannot get it to work for me for more than a minute or two on my normal high graphics settings or my normal medium-high FSX settings, without getting horrible graphics glitches. I see from the various feedbacks that many of those who are having success are doing so by turning down settings either graphics and/or FSX or clearly state that for example they don't use autogen or the resolution was turned back to a lower setting etc, etc. I can get smooth by turning settings down, until I get smooth. without the need for any BufferPool setting appearing in the fsx.cfg but to me that is NOT the point. I want completely smooth at my preferred settings not downgrading to suit... that is my idea of the holy grail. I get different performance levels for different types of scenery and aircraft. I assume this is the case for all simmers. I get absolute smooth, clear crisp, sharp performance with photoscenery and lock at 60FPS and dont use FPS Limiter. Any scenery like GEX with Dense AG I use FPS Limiter because AG I think is a cause of micro-micro-stutters along with AI, and the limiter smooths it out compared to NOT using the Limiter programme. I also use EZDOK and when in the VC with the vibrating going on I cannot see evidence of any micro-stutter !! So to summarise, what is it we are looking for with this tweak, which cannot be achieved by downgrading settings without the BP insert in the cfg ? It's beginning to look like the objective is to get your FSX to work with the BP=0 entry whatever the cost to settings. The point being....?This is not a negative comment. I just want reminding of the objective here.Regards

Thanks Jaycee for the reality check. Sometimes when trying to fight off the alligators we forget we were there to drain the swamp (or however that saying goes).Stephen

Amen to that. What makes it more dificult is that what I see as smooth, you may see as jerky and vice versa. We are talking a PURELY SUBJECTIVE situation here. It's a nice exercise and it has created probably the longest thread in AVSIM history but in the end, it's just another tweak thread. Try it, if you like what you see - great - if not - still great.My objective has always been good visuals and smooth flight. I couldn't care less what the framerates are doing as long as the flight is smooth. If I fly into LAX during a thunderstorm, I know the frames are taking a hit but since I don't fly with the frame counter showing, and the flight is smooth - who cares?At least we didn't waste reams of paper on the subject.

My guess is that the road is most important, not the goal. I've followed this thread from the start and it seems that the process of experimenting with different settings and ratiocinate regarding causes and effects is fascinating. I guess the goal now is to determine what BP=0 really means and why the setting do work on some systems and not on other systems. In that process people sacrifice IQ to make the setting work, which seems to be the goal at the present.Stephen's comment

is very apt.It would be interesting if we could get some expert informatin on what BP=0 does with FSX on a system from a former ACES team member.The setting doesn't do any good on my system and I'm not participating in the quest for the holy grail, but this thread is very fun to follow.

OK, let me try to explain as to why:BP=0 gives as proven more performance by (technically) bypassing the internal buffer and sending the data directly to the GPU - or so it has been said. For me, this tweak bring tremendous performance jump, we are talking here about 20-30% in FPS area. Why FPS? Because for me, visually, nothing below 30 is smooth. I want to get my FSX to work at 30fps 98% of the time, and BP=0 allowed that. Now, it's a fact I must not overload the GPU buy sending it too much data, thus I had to reduce the extreme settings - TML=1024 instead of 4096 and default LOD radius and not 8.5 or so. Basically with default max. settings, AG=Dense, Scenery=Very Dense (what I had previously too, I don't need max), the BP=0 is working beautifully, and my FSX has more FPS than before.I have basic stuttering in FSX, which is there with or without the tweak. Never managed to get rid of it, and there might be something even inside of FSX causing it, but I never got around to test it. Maybe once...The best performance, and FPS almost never drop below 30, is with the tweak on and with settings as they are. If I would remove BP=0, I get very much >30fps situations, very very often...

The way I see it is that BP=O is a dramatic increase in performance for some users and a work in progress for others. Some have decided to eliminate the BP tweak and just focus on flying.I can't fly with poor performance and/or micro stutters. For many i7 users the BP tweak means the difference between smooth flight and stutters.I'm grateful that I found a balance. I found the right OS, system, video card, drivers and the appropriate cfg tweaks.Now I'm ready to finally enjoy FSX.That is until my next upgrade.

Word Not Allowed,Have you tried upgrading your chipset drivers?Jose

I'm now in sim heaven thanks to MSFS 2024 and hundreds of add-ons!

If you can't eliminate stutters with your system, you sure have some problem with your system. IMO a smooth flight is the main goal for any tweak.I'd suggest that you (revisit) this post by Nick Needham: http://www.simforums.com/forums/forum_posts.asp?TID=29041Do you get the expected results out of benchmark programs (SiSoftware Sandra, SYSMark...)?Or is that simple that you try to run FSX with too high display settings? Have you tried to decrease the display settings to enable a smooth flight? Maybe this is your holy grail to a smooth flight?

About the FSAA, most let enhancer do the AA, but as stated in the enhancer help, it states that the best way is to use the application FSAA, because it tells the driver where to apply AA and where not, so it seems that using enhancer puts a rigid AA on all and where using FSX AA, it gives explicit info on to where not, possibly giving a performance gain, giving the GPU more room to interact with the BP=0.Maybe some find the FSX AA worse, but I dont see any or a tiny bit of difference here. Except, the FSX AA seems smoother a little bit.I have a mediocre system, E6750 with a 380mb 8800 GTX and do see some differences with the BP=0. It is here not faster, no more fps, but just a slower drawing of textures. At BP=500000 it keeps up, and at 100000 it is too slow.Strangely, no artifacts at all, whatever BP settings I use. Maybe a slower system cannot saturate the GPU.Anyhow, still following this, and what strikes me is that who have the fastest CPU's speak of artifacts, and not so the older systems.(rant)The most disturbing things is that I have a real BIG fps drop is when there are some building to been drawn, like an default airport.Flying the Airbus at altitude works well, but any 'normal' airport drops like a bomb.Do all for example, Aerosoft EHAM users(!) have the state of the art PC's ? did Aerosoft guys really tested FSX with their EHAM or another major hub, and a addon jet ? whatever which ?or are they just interrested in selling, and disregard any complains on performance, something they cant fix not have any influence on ?Flying a GA is nice, fun and good, but jets seems a problem.Now, its the same old song, from DOS to FS98, to FS2004 and now to FSX.. always been overtaken eventually with the fastest PC's. I am getting a bit tired of upgrading, and not been satisfied, until years later.But that seems the way it is in this hobby..(/rant)Keep on seeking to the holy grail, and maybe some may setup a good testing tool, where we enter our settings, with a controlled flight.Johan

Of course. I'm pretty much tech-savvy when it comes to setting up computers... the stuttering comes in my opinion either internally from FSX (something causing it), or overloading.

Word Not Allowed,You can try these 188.25 Vista/Win7-64 modded beta drivers if you like, should enable you to fly stutter free at highest performance compared to any other NV driver no matter your settings even with out any BP in the FSX.cfgMust Follow the Directions to use these and I dont know if they support multi monitor display:You will have to download the driver and then download the modified inf file from the same page, extract the drivers into a directory, then copy over the inf file with the modified one and then install them as you normally would --non whql so bypass the "not compatible" screen and your on your way. A bit less filtering quality, but you be the judge on what side you want to balance things.

too high of a tbm setting causes stuttering for me

What's the deal with these drivers?! Why would they be so much faster?

I dont know the why.They were modded laptop drivers to run some other DX9 games that also stutter on Vista/Win7-64, in FSX at full settings the FPS diference is about 100% the same as with BP=0 with no stuttering except you can remove BP from the CFG and let FSX do its own BP thing,--> as long as you can live with the filtering shortcuts, they are a huge step above anything you will ever find.Make sure you follow the instructions as I posted above.

Um, what'ya mean with filtering shortcuts? Less filtering, meaning less picture quality or something?
