So I'm flying training mission 6. All other 5 missions went off without a hitch. I have a damn good lap-top running this game so it's not a graphics issues. But in training mission 6, the dogfight, when the Albatross gets about to float across my cross hairs, the screen stutters as if I just took a screen shot and the enemy is beyond the cross hairs when it recovers. Any ideas???

Hello again, everyone..

I know I complain alot, so I apologize for that, and would like to congratulate Neoqb and all involved on giving us a fantastic simulator. Best sim ever, I think...

I am having the same problem, accompanied/proceeded by the sound lagging, or more like starting the stutter. My sound goes haywire when the stuttering starts, and then I get screen pauses, that make it unplayable. I'm wondering if it's a bottleneck due to only having 2GB of RAM? Or should I get a processor, something better than this Pentium D 945 3.4Ghz? I've tried lowering everything I can think of within the game, and in Vista..

Any ideas, anyone?

I stepped up from a single core to a I7 920 same 8800gt gpu and it has made the game very playable even with 40 planes in the air.

Thanks. The 945 is a Dual Core, not a new one, by far, but it runs some missions great, like #6, ( I am having trouble near the front or with the Se5a mission "Morning Hunt" (very cool mission, BTW. Beautiful sim..) Time for some processor research, I guess.

As far as I am concerned, this game is nearly unplayable without a quad core. My dual core AMD processor is almost always at 100% cpu usage on both cores with this game. FPS are pretty poor and there are delays, stutters, and sound problems. Perhaps people with more optimized or merely better dual core systems are running the game fine, but for me there will be a substantial investment in hardware in the future to be able to play this game in the manner that it was intended.

Agreed, Foucault. This cpu stays maxxed out, too. I googled...something...yesterday, and came across a post at RoF forum about doing a dual boot setup,with Vista already installed, and that it flat cured the problem. The guy said he's running it nearly at full detail. That's where I'm headed first.

I would say your problem is more related to your amount of RAM than your Processor.

Im running a core 2 duo @ 3 gig. I get around 40 fps with all settings maxed.

Vista is a hungry beast and its going to take a fair chunk of that 2mb. Im running XP

Run it with your soundcard Disabled from Device Manager, to check if this stuttering is caused by soundcard problems. It would tend to rule out soundcard drivers if RoF is still stuttering the same with the soundcard disabled (including motherboard sound which can be disabled in BIOS setup)

Thanks, Ming. I'll try that here in a while.
What kills me is alot of the missions that came with ROF and getting the Se5a, I can run with all setting maxxed, without so much as a hiccup, and some choke every few seconds. It's a fantastic simulation, though, and I'm thankfull I CAN see it and play alot of it on high settings. It'll still be here when I get XP or can afford to upgrade the box....

You can not exchange your mobo in your DellE521 because it is a BTX board!!!!
I have more a less the same rig as you, you can overclock your DellE521 by using clockgen and stay away from Vista!!!!!!

CPU: AMD Athlon 64 X2 6400+ OC to 3.5Ghz
GPU: Sapphire HD4890-1Gb VaporX
RAM: 4gb Crucial ballistix PC2-6400
PSU: Corsair TX750W
WOS: XPsp3

Thanks for that, dutch. I have never tried overclocking and probably never will. Not willing to risk it nor buy a custom cooling solution.

I am curious if you find that 1 Gb video card is providing much of a difference. With my 512 Mb card I have, I can almost max everything out and post-effects and not hit above 100% video card memory usage as indicated by the settings editor in RoF.

My impression is that RoF is much more CPU limited than GPU limited.

I get decent performance in smackdown with my dual 3.2ghz E8500. Apart from loading pauses at the start I get smooth very playable fps. I'm not sure what matters more for ROF in mid range cpu's high mhz or quad core.

From Riva Tuners logging page ROF seems to be using all 768mb of my video memory event though with landscape set to medium, the setup page says 31%. In free flight ROF uses between 80-90% of my dual core E8500 at stock 3.2ghz, smackdown has my cpu usage at max. I have noted that all the logging takes quite a bit of cpu power, ROF runs much worse with Riva Tuner logging active.

I'd be interested to know if anyone's seeing less than 100% CPU usage in the smackdown mission, I suspect not even with the top level quad I7's.

I would, too. I disabled my onboard sound, and I haven't gotten the wierd sound distortion even when the stuttering starts, which seems MUCH less since the last patch, but it's still there. This Pentium 945 just barely cuts it.

Foucault, You can do OC using Clockgen it will not harm you if you only use it for playing RoF do on beforehand a stab. test to determine how far you can go in Ghz. You can use Prime/3dmark etc for this. Max CPU temperature can be fund on AMD website.

You are right RoF is not that high performer when it becomes to graphics, (ever seen Killzone2 on PS3 and you know what I mean inhere). According to a RoF member, the game is designed for Quadcore systems, so your impression CPU is much more limiting the game then the GPU is right, when you have only a duocore CPU.

I'm running 4Gb RAM and a SapphireX HD4890-1Gb I have no complains regarding the graphics for the OFF3 and RoF game.

BTW what brand video card do you have, because the big Dimension cooler house can block the Video card.

Thanks for the info. I may give it a try if I feel brave. BTW, video card brand is VisionTek. Speaking of blocking, the size of my case is an issue as well. I can't fit a large video card in the case length-wise.

I know, and you can not install a non stock Cooler because it is a BTX case. Some guys who using the Dell cooler just cut out the black cooler casing at the bottum to make room.
You can watch some Dell E521 modification at Computerwine blog see:

Just a heads up, NewEgg has the Nvidia 9600GSO (96 stream processors) for 39.99 (after a 20.00 mail in rebate) I have installed two of these and they work great with Rise of Flight. One went into a buddies AMD 5000+ (Early dual core, Dell E521) and is smooth as butter all on high (except the ground I think, that is at medium) and into my Simpit on a Quad Core 6600 and this flies it all high (even the ground). If you need a decent video card cheap, this one works. I have not come across the stuttering problem with either computer, nor on my Core i7.

Edit: Price is 34.99 right now on sale.

Not to be ungrateful but I seriously doubt that adding a 30 dollar video card will improve my performance considering that the Radeon HD 4850, which is still selling for over 100 dollars, has 800 processing units to the 9600's 96 processors. The 4850 has a higher memory clock and core clock than the 9600. So you'll forgive me if I think I better served by the 4850. If neoqb can't program for an ATI card, that ain't my problem. I'm glad your friend's system runs smooth as butter, but mine does not and an inferior video card is not going to fix that.

Sorry about that Foucault, my message was intended for those who wanted to upgrade thier cards after experiencing stuttering.

My mistake as well. I hope others find this information helpful.

I have same problem, in Win Xp run well, but in Win7RC and in Win7 Ultimate suffer stutters and sound reverberation, i tried differents solutions and for the moment not found fix.

This issue is not problem for specs, if can run well in XP, system powerfull is correct.

In my testing, i think is problem of Asus/Intel Chipset drivers or Asus/Realtek audio drivers.

Last night i try to installing drivers of Motherboard, remember im using integrateed Realtek sound, with audio drivers of Realtek (not ASUS) installed and updated. After install driver of Motherboard (chipset) i try to play RoF and OMG run well, no stuttering. After i reinstalled Audio driver of Realtek and try RoF, but return to stutters problem.
After this i tried reinstall Motherboard driver, but i canīt, i tryed uninstall audio drivers and installing old drivers, but not fix problem, after all i restored Windows 7 to point in back have no installed ASUS motherboard drivers. Ok now install ASUS motherboard drivers and NOT install audio Realtek drivers, but this now NOT fix problem.

With all this, i think problem is in Motherboard, in integrated Realtek sound. The simple solution buy soundcard is not valid for me, i not have money for this buy (bad times).

POSIBLE SOLUTION

I tried launch RoF in compatibility mode with Win XP SP3, and issue disappear, now RoF run well.
