Hi,

 

I had a major update on my PC components almost a year ago. I have an i5 2500k system that is running on 4.5 ghz and a GTX5 560Ti graphics card. My RAM is 2x4 GB DDR3. I am running PMDG NGX+UT2+ASE and especially on busy airports like Heathrow (with Aerosoft scenery) I am getting quite low FPS (12-13) with stutters. Do you think I should be switching to Ivy Bridge or update my Graphics card to solve my stuttering problem?

 

Cheers,

Hi according to reviews ivy has little to no effect on fsx intact it heats up more on a lower clock speed.

Your system is fine in fact mine is very similar to yours, the only thing you will need to do is tweak your fsx CFG using kostas guide believe me it work and it helps.

Hmmmm... a faster GPU would help a little for the payware scenery/payware complex planes, but I don't think I'd spend the money myself.

 

I'm in the same boat as you but I plan on keeping these parts for another two years at least. I've found with high settings it's tough to get more than 15 fps at big payware airports with complex planes and AI, and weather, and LOD, and autogen and etc etc... hehe

Hi guys thanks for the ideas, I tried Word Not Allowed's tweaks and really they seem to make a difference. I was wondering whether it would make sense to go for an update, but with this info I will keep it for a while.

 

Cheers,

It really comes down to money at this point. You've got a nice system already... the only thing that would make it faster (and the gain wouldn't be that much) would be IB i5 3570k or i7 3770k, with a GTX680, and 2400MHz ram.... overclocked to 4.5 - 4.8. Clock for clock IB appears to be slightly faster than SB but at higher temperatures. However, IB seems to take advantage of the faster RAM and some users say FSX is stutter free.

Probably I will stick with my current setup for a while and try to push it up a notch, perhaps 4.8 GHZ (I am counting on my Noctua fan here ) for the CPU and overclocking the GPU. I was quite annoyed with the stutters in Heathrow during the final approach but even Word Not Allowed's tweaks helped to reduce them. Thanks for the help!

IF you don't have an SSD, maybe an upgrade of moving your FSX to the SSD would help. Other than that If I were you, I would stay with what you have and wait for the next gen of CPU from Intel and skip the IB. I would also maybe try to OC to like 4.8 or something like that maybe.

Thanks MAnny, I have a SSD for my FSX, and quite happy with it.

Murat, have you any cfg tweaks eg. the Bufferpools tweak?

Yes Howard, after Bilal mentioned above, I tried Word Not Allowed's tweaks and I think BP and vsync tweaks had a great effect in reducing stutters.

The scenario you describe that you want better performance in is mainly due to lack of CPU power. CPU power is affected by IPC between different CPU arcitectures, clockspeed, cach size, and RAM transfer rates.

 

You already have a good CPU architecture running at a a high clockspeed. The i5 has slightly less cach than the i7 but we dont really know how much this affect, and you didnt mention what RAM you are using right now. So an upgrade to a i7 3770K with high performance RAM will only make a fairly small difference. Haswell will hopefully make a bigger impact within the next year.

 

But if you want to spend your money now it should be on an 3770K and 2133Mhz or higher DDR3 RAM. You already have a s1155 motherboard and you can sell the i5 so it doesn't have to be that expensive. Especially if you already have high performance RAM.

Thanks, at the beginning I was considering i7 3770K also. Probably I will keep the money and wait for next year to upgrade. My RAM is 1600 Mhz, so an upgrade on RAM also will be required.

It would be interesting to test say my system against the OP's in the same scenario and see just what performance difference Ivy Bridge + fast RAM can provide. FSXMark results show about a 7% difference at the same clockspeed, so throw another 10% clockspeed on there and you're close to a 20% performance difference (perhaps more with the different GPU as well). I say this not to brag but purely out of curiosity.

It would be very handy with a pure CPU benchmark. FSXmark11 was designed to test both GPU and CPU but with todays fast GPUs its mainly CPU bound anyway. The first few minutes of the FSmark07 flight path with some relevant high slider settings is in my opinion a lot better as a pure CPU benchmark.

That's a good suggestion, thanks!
