Hey guys, I've been searching around and reading tons of helpful guides on using the Bufferpools tweaks in my fsx.cfg file. I've tried using UsePools=1/0, Poolsize=0/490000000 (and a few in between), as well as RejectedThreshold=131072. I've messed around with plenty of different combinations of the three, enabling one while the other is disabled, tweaking values of one or the other and testing, etc. However I seem to be at a standstill. For testing I'm using BluePrint Simulations' KLAX, along with Aerosoft USCitiesX LA, and flying the PMDG 737-800NGX. My problem is this: no matter how much I mess with these three tweaks I'm not seeing ANY boost in performance, and on top of that, according to GPU-Z I'm still not even using more than 1005MB of my 2048MB GTX 550Ti. Here are my specs: ASUS M4A79XTD Evo MOBO Kingston HyperX Blu 4GB 1333Mhz AMD Phenom II X4 840 OC'd @ 3.5Ghz EVGA GTX 550Ti 2GB OC'd @ 1000Mhz Core 2040Mhz Shader Windows 7 Home Prem 64Bit With my video settings, which are tweaked quite a lot (I average around 25FPS and my game looks and runs GREAT, mid flight, except in some of my CS and PMDG aircraft and near large Payware airports). I'm just trying to get a nice little boost on the ground and near bigger hubs. My tests at LAX were giving me around 11fps on the ground in the NGX. BARELY playable. Not very smooth at all and it makes it quite hard to make precise control adjustments when your skipping along at 11fps... Is there something I'm doing wrong to not be seeing ANY fps or smoothness boost out of these tweaks?? My video card certainly isn't reflecting that I've even done anything at all!! Never goes above 45% mem usage. I know it can handle it because I'm not even using half of my memory normally! Any help would be greatly appreciated. I've been working on this for a while trying to figure out what's going on. Also: I am using Bojote's tweaked config file as well as HighMemFix Thanks in advance! Brick

hey all, Since I am the proud owner of a GTX670 4Gb Edition and a i7-3770K I am able to enjoy fsx way more because of the awesome performance I get out of this rig. but I'm still experiencing a little stutters and I think it's because of the bufferpools entry in my fsx.cfg I'm using UsePools=0 and the default RejectThreshold from the Venetubo fsx tweak. So my question is; is there any best recommended setting for those two tweaks to achieve super ultimate smoothness in fsx? much appreciated! specs: CPU: Intel Core i7-3770K GPU: Asus GTX670 4Gb Edition HDD: Crucial M4 SSD Mobo: Asus Z77 Sabertooth Mem: Corsair Vegeance 16Gb DDR3-1600 FSX: Gold Edition with PMDG737 (I always fly it) -
Hello Recently was reading an article, courtesy www.rastek.com about bufferpools suggested by Steve. A part of the summary goes as under : The general rules are:- 1). If the GPU is very fast, and with a good-sized memory, say 2 - 4 gig - it can eat all of the incoming data and wait for more, so we allow the GPU to give everything its own buffer by UsePools=0. To control any spiking, lowering of the IQ sliders in FSX is the best course of action. 2). If the GPU is kinda "medium-range" - a 660 or 670 - fed by a 4.6 - 4.7-gig CPU - then we should use UsePools=1, making all buffers shared. In this case - as with most systems - this will be, or what should be used, and by adding a RejectThreshold - a small number - say 262144 (256kB) under the UsePools =1 line. It will look like this:- RejectThreshold=262144 The RejectThreshold will act as a throttle, by allowing the creation of dedicated buffers - which is then of course, a little bit of UsePools=0 mixing in - it could mean that 20% of the buffers are now dedicated, while the other 80% are shared. If we make that number smaller, then more dedicated buffers will be created, with the resulting improved performance. In this example (above) this number - 262144 - might be perfect: if not, then larger - or smaller - number will show the way. This needs the user's testing. Spiking will require lowering of the IQ sliders in FSX or increasing the size of the RT, or raising the size of each buffer. 3). If, however - the CPU is stronger than the GPU, such as a 4.5-gig CPU feeding a 560TI with only a gig of video ram - we will definitely need UsePools =1 for sure, but with a big-ish RT, say 1MB (10485760). Other larger or smaller numbers and testing will show the way. My config is a i7 2600K @ 3.40GHz o/c to 4.40GHz using the standard o/c option in the bios. GPU is GTX670 and 8GB DDR3 RAM @ 1600Mhz (not sure about this since invoice says 1600MHz whereas CPUID reports it as 802 MHz) I am a bit messed up between the suggestions in point 1 & 2. Point 1 suggests that with my kind of GPU, I should be using UsePools=0 whereas Point 2 suggests that a 670 is medium range and therefore I should have UsePools=1 What should I actually go with? And if you suggest UsePools=1, what PoolSize & RT values would you suggest. Ted

Hi, I have had FSX installed on my "new" pc (specs in signature) for about six months now, and I have gone through endless forums on how to improve performance, and I have managed to get my performance up to a pretty good level (most scenery settings maxed, all traffic except for GA at 40%). I use the BP=0 tweak, but I tend to get artifacts when panning. When I try to use bufferpools or delete the [bufferpools] section in FSX.cfg (Rebuilding didn't help), I get endless stutters in wing, spot, and locked spot views (I have enough VRAM-2 GB). Yes, I could turn the settings down, but I have already tried that . For some reason, I have actually seen a performance decrease when turning down autogen, and traffic has no effect until it is set to around 75-80%. :unknw: Does anyone have any suggestions? I think it is my GPU, because I routinely see usage at 90-100%. Thanks!
