SFR is the standard recommendation for IL-2, the microstutter is common with AFR.  From the battle-fields.com link I posted earlier, water=2 vs 4 does have a noticeable impact, but UP2.01 with mods does not.

So, from my testing, it's Avg: 71 Min: 22 Max: 142 for CrossFire enabled 16X AA 1920x1080, but no scaling over a single card.
and your testing...........Avg: 79 Min: 28 Max: 197 for SLI enabled 16X AA 2560x1600, only 35% scaling increase on Avg fps.

Thanks again

Thanks again

Not at all.

Is your CPU overclocked? You got a excellent minimum (my CPU gets 28 but with 4.15Ghz -older generation-)

[Porksmuggler]

I'm only at 3.2GHz, 20x160, 1600 on the RAM.  The minimum is the same with any of the above test, I suspect it is CPU bound.  I just tested as you first did with SLI disabled, Water=2 (always for ATI), and Effects=2:

Mine.. Avg: 74 Min: 22 Max: 173 Crossfire disabled 4X AA 1920x1080
Yours  Avg: 63 Min: 29 Max: 145 SLI disabled 4X AA 2560x1600

Half a GTX295 should be roughly a GTX260+ Core 216, which looks good for such a high resolution.  I will likely build with the new GTX 460 (priced close to the GTX260 currently) for sim fans, in case they get hooked on IL-2   Not sure I can recommend SLI though, price vs. performance is not a good ratio on this title (of course CrossFire is pointless though it seems)

Well, +35% (in a benchmark not ideal for me) is a good figure. Moreover, I use the biggest resolution, and in this and other games, SLI is one way to go (not the only one). I'm considering to change my CPU, RAM and MB. My idea (I'm not sure) is a i7 950 with Gigabyte X58 UD7. Not considering to change my GPU at this moment. Maybe with next ATI or Nvidia generation.

About the GTX295, I think that the correct GPU ident. would be 2xGTX275 with 260 frequencies. Look at shaders.

[Porksmuggler]

+35% is better than 0% so far for CrossFire in IL-2!

off-topic to ATI thread, but anyway.  I would hold off on the platform change, since you've waited this long, with the LGA-1155 Sandy Bridge replacement of LGA-1156 so near, price changes should be soon as Sandy Bridge will compete directly with the older LGA-1366 Bloomfields like the i7-950.  After countless builds, I only use Gigabyte and ASUS for clients, but ASUS for personal builds.

I would keep the GTX295 also, nowhere really to go yet, and who knows how far Oleg will push SoW.

Yes, more like 2xGTX275 by shaders since you are overclocked, at stock performance roughly the same as GTX260 Core 216 SLI.

No. GTX275 has got 240SP (shader processors) cores GPU, and GTX260 (v.216) only had 216SP. Cores are more in GTX275,s. With GTX295 you get 480SP (2*240), no 432 (2*216).

GTX295 are two GTX275 in SLI with lower frequencies (until you OC it).

Thank you for your advice about waiting for SB. But I have read that OC will be more difficult and the substitute of 1366 wil be the new 2011 socket (2nd Half 2011). Near a entire year to come.

Regards.

[Porksmuggler]

lol, we said the same thing "yes, more like 2xGTX275 by shaders" and "since you are overclocked" by clock too.  Stock performance is still roughly GTX Core 216 SLI, yours is OC'd to 2xGTX275.  Nip a shader here, clock a little different there, you get the entire 2 series

The replacement for LGA-1366 is LGA-2011, but advances in LGA-1155 will make it direct competition for LGA-1366.  Same article, or I can provide others...

I'm not really recommending the LGA-1155 for overclocking, but it's release will impact sales of lower and mid range LGA-1366.  That means price-drops before phase-out Q1 2011.

Hi all

Did someone here try to use "Crossfire Extention" tool to force and control Xfire operaton and methods?

gprr

[santobr]

Enable crossfirex in ATI drivers.
Turn off hardwareshaders in IL-2.
Copy the file "il2fb.exe" to "quake4.exe" (don't rename it and don't delete it).
Run the new file quake4.exe and you will see a real crossfirex with IL-2.

But remember to take note of the FPS without hardwareshaders before run it in crossfirex mode and turn off the "wait for vertical refresh" for comparison purposes.

santobr.

I tested the 1.4 version, all methods, AFR, SFR, etc.  It even had a profile for IL-2 already.  No changes in frame rate, but I didn't need 16XAA enabled for the CrossFire logo to display, like otherwise.  I did not test with hardware=0 as any improvement from CrossFire would not be worth the image detail loss.

I did retest with the CPU overclocked, and saw improvement with clocks approaching PA_Willy's 4.15GHz.  I haven't gotten around to testing at 4GHz yet though.

PA_Willy  Avg: 63 Min: 29 Max: 145 SLI disabled 4X AA 2560x1600
Mine...... Avg: 74 Min: 22 Max: 173 Crossfire disabled 4X AA 1920x1080 3.2GHz
Mine.......Avg: 81 Min: 22 Max: 184 Crossfire disabled no AA 1920x1080 3.2GHz
Mine.......Avg: 82 Min: 24 Max: 180 Crossfire disabled 4X AA 1920x1080 3.6GHz
Mine.......Avg: 88 Min: 27 Max: 206 Crossfire disabled no AA 1920x1080 3.6GHz
Mine.......Avg: 94 Min: 28 Max: 221 Crossfire disabled no AA 1920x1080 3.8GHz
Mine.......Avg: 58 Min: 28 Max: 71  Crossfire disabled no AA 1920x1080 3.8GHz v-sync enabled (my current setup)

The bottom line is the game needs v-sync, doesn't really warrant SLI or CrossFire setups, and really benefits from high CPU clocks the most.  A totally expected conclusion for a decade old title...

I agree. Fantastic results in your i5 platform.

10.9 Drivers are out for d/l and as far as I can tell are working better than 10.8, and no blocky text as well.
