I really don't get it, I cannot get RoF to be even remotely playable. When running any of the 3v3 quick missions Fraps shows my frame rate stays pretty consistently around 60, sometimes it goes as high as 80, occasionally it drops into the 40s but only for a split second.

Now even though I'm getting numbers that I should be ecstatic about in the upper right corner, the gameplay is so choppy that I can't even fly the plane, much less fight. The choppiness is bad enough but on top of that I'll get pauses of 3 to 5 seconds and sometimes lose either track ir or joystick/pedal control for about the same period.

I've updated drivers, reinstalled, tried different drivers, tried different settings, nothing matters. Any suggestions?

My specs:

C2D e6850
Asus P5K deluxe, using onboard sound
GTX 280
4 Gigs RAM not being entirely used by Vista 32.

Have you tried dropping the sound settings? I seem to remember when I first got RoF I had similiar issues with choppy unplayable Frame rates, I think dropping the sound quality to low fixed it. Haven't had any issues since.

Oooh, the high frames rate stutter!

By chance do you have a Creative Labs sound card?

If so, and you can live without quadraphonic whooshes, turn off the EAX and other enhancements. They caused the same symptoms in my system, and cleared up as soon as I ditched them.

Nope, using onboard sound. I've got low quality sound set and 32 voices. I've tired setting 16 in the cfg file but it doesn't seem to work.

I really don't want to give up on this game for the dozenth time... frown

Okay, I just popped into the sim and it was an unplayable, horrible stuttering mess. Made a track file of it so I could see if I was improving things or not as I went to tweak.

Yesterday I installed the drivers for our new printer, and on a hunch disabled the HP monitor software.

Replayed the track and it was smooth as silk.

Replayed the mission and it was smooth as silk.

So I'd start looking at background apps, and see if you can disable any of them.

Dart, you can have quadrophonic sound without EAX! That's how i fly all the time. Beside that, does ROF support EAX? IL2 does but i think RoF not.
I still wonder why there are so many problems with Creative cards. The devs had enough time to fix the issue. Other games run wihout any problems either and Creative cards have the best sound, atleast the X-FI ones. I think Lefty even suggested to drop the X-FI card and use onboard sound to "fix" sound related issues. I thought that was a joke, as dropping a dedicated sound card for onboard sound is alwas a stept backwards.
Doesn't make onboard sound the games slower?

@Jeevz. There was a thread soem weeks ago, where someone tested the performance with high and low sound settings. The conclusion was that the game runs faster with high quality sound. Don't ask me why but i would recommend to raise the sound quality.

Oh, I've got the X-Fi card - and no, I'm not disabling it.

I have found that some games and sims run much better without the sound enhancement crap running. To be honest I can't really discern a huge difference in quality with them turned on in the first place!

With the processors and large amounts of RAM today, sound cards are no longer a requirement for high performance (the CPU overhead is tiny now compared to the good old days) - they are now for higher quality.

My new system (fedex tracking number!) won't have a sound card. I use headphones exclusively, and so most of the functionality would be lost on me. Creative Labs has had some driver and software issues over the last couple of years that have made me really sigh as well.

Thanks John I'll try that.

I killed a bunch of processes that weren't using any CPU or memory but may have been conflicting last night and it ran a little better.

I'm off to the Redneck Riviera today but I'll continue working on this when I get home.

But onboard sound hogs the system bus. A dedicated sound card doesn't use up CPU cycles but calculates everything on it's own. The X-FI is the fasted soundcard around with its own onboard RAM and there is a reason for that..high quality sound is processing intense and slows the system down.

I wouldn't disable it either! smile To be honest...when i have read the comment by Lefty to disable the card i thought he was crazy to even make such a statement. For him it was a "fix" for the sound issue. Well....

I'll probably spring for one later down the road if I encounter problems with performance.

But if an i7 960 running four cores at 3.2 GHz can't provide enough muscle (with 6 GB of RAM) to run the sim decently, I don't think a sound card is going to help much.

(trying not to hit refresh on the FedEx tracking number)

Well more tweaking and tried running the sound on high and it runs better now, if I fly a career mission near the front bizarre things happen, AI planes go from slow motion, to fast forward to catch back up then back to real time before doing it all again, and my controls or track ir intermittantly stop working (Fraps says 40-70 FPS through all of this)...

BUT!

I can play all the quick missions smooth enough to have fun in the duel or 3 v 3 dogfights so I'm at least happy about that.

look at the control options and check if you have Force Feedback ON/OFF. If you don't have a FFB stick, turn it off as it has been known to cause issues.

Yeah I shut that off during my tweaking. I think it's the onboard sound, I've had issues with it and RoF since the game came out.

I had stuttering a couple of months ago with an Nvidia 9600 gt 500 MB card. I fixed it by using the compatibility option of XP3SP. Last week I changed cards to a Radeon HP 5750 with 1 Gig Ram. The stuttering has returned and the compatibility option doesn't make any difference this time. I even tried a complete reinstallation of ROF. Made no difference at all. I have an intel core duo cpu. I had supposed this issue was fixed!

I haven't found a solution to the stuttering, as this shows on my nice shiny new Radeon HP 5750, if anyone is interested. None of the above suggestions work. None of my own experiments work either, too wearisome to mention in their banality and dullness. Only thing I have noticed is that raising the sound quality seems to make the guns go quicker and to speed up the stuttering. Fast or slow however it is still the same evidence for a conflict somewhere. No real ideas at all as to what it is.

May try this. I went to my Sound Device(Realtech) properties. Clicked on Advanced. Unchecked "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority". Lowered my sample rate and bit depth to 16 bit, 44100hz (CD Quality).

I run everything maxed out except Landscape which is at Med and I get 22-30 fps during dogfights. Sometimes higher and my system isn't a powerhouse.

Graf thanks for the suggestion. I tried changing these settings and found that with the sound off entirely - with no sound running at all - the stuttering disappears entirely too. However, I couldn't get your solution to work. But I think this assumption is correct; it is a sound/drivers issue. I am running Windows 7 and my onboard sound drivers only went up to Vista. There are no later ones and so I had a few problems during their installation - but I thought I had it sorted out. I wonder if the RoF people can give us some options in terms of the "exclusive control of device" check. Anyway, I have given up for now, all this fiddling around is just too too boring.

With the sound fully disabled the stuttering goes away almost entirely; the occasional pauses can be explained as scenery loading and such. So I have decided to get a sound card to replace the onboard sound. Not expensive solution, I just hope it works ok.

In short, so it doesn't appear to be a Microsoft Windows 7 / dual-core problem at all, contrary to the RoF engineer's assertion in the interview, but - at least in my experience - a sound set-up issue. We will see when I install the card in the next few days.

I have finally got rid of the stuttering it seems. The sound card, with the onboard disabled, did the trick along with running the sim in xp compatibility mode. Oddly the on board sound set up was ok with my previous graphics card, the Nvidia. With the ATI 5750 it was not.

I have a Creative Sound card, but so far my play has been relatively stable...... with the ecception of when I play one of the instant missions. As I enter the city's dogfight area and I start dogfighting an opponent I'll get one or two several second freezes. After that it's fine and have no issues. Considering the ancient computer I have I'm happy, but if I could manage to stop these freezes I'd be ecstatic.

Can you give me an idea on how to turn off EAX, etc? (IOW.... is this done through RoF or through Creative's Control Panel?)

Thanks.
