Made FSX use all my 1gb video card!

[Pepere]

Normally FSX only used about 1/3 of my 9800GT 1GB graphics card memory. What I found was that by Adjusting the "BufferPools" up to 160,000,000 (with out the commas) let FSX use all of the 1gb memory. Don't know if that number is optimum but I Kept raising the amount until FSX use the full 1GB. It does not use the full 1gb all the time but it would spike to 99% at times and had a 60% + use rate most of the time. I used the program "EVGA Precision" to monitor the usage and ran FSX in the Windows mod so I could monitor EVGA readouts. Interesting!

Sounds interesting. What were the benefits you got from it?

I'd guess it takes some of the strain off the cpu onto the gpu.

Here's some more info on BufferPools:

Don't know of much but I do seem to get less stutter. I've not run it this way for that long so not sure. But I would think (???) having the use of more memory would be of some benefit at some point? I'll do more testing. From others it seems that setting the pool to 0 gets you the best results. But when I did that the Card memory was register as "0" usage. I think that tweaking gets you just that a tweak and that's all? :mixedsmi:

Pepere I tried it last night and it is an improvement for me. I have a GTX285 2 gig card and i noticed that my pan rate is better in that it does not stutter when I pan around . And I have no more spikes when I pan around . so it seems to work for me. Thanks for the HU :salute:

I am running a ASUS 5870 video card (Matrix). Although at one point I had considered "tweaking" it's settings, I never did.

Is it worthwhile attempting this?

I dont think it would do any harm. If it doesnt work just put it back to what u had it ar before. Might not help at all and it might improve. With fsx who knows why one tweek for this guy works but doesnt work for that guy. ?

Did an hour flight last night and my FPS seem better and no noticeable stutter. Stutter was getting to be a big problem with my system. For now it seems good to go. Later I'll do a flight into JFK to see what happens there.

I wonder if this would help with an ATI card? I'm getting some stuttering in mine, too.
