Not certain why but now my vid card will only operate at idle in game. FPS took a big hit, not acceptable.

I have a ATI HD4870 X2 and was getting great FPS until tonight when I first flew this patch.

I went into catylyst and everything is where it has been prior and in the RoF game settings I left all settings at the default for the first flights, actually a relaxed setting since I always maxed out all the sliders before.

Ran Riva Tuner to see whats happenning and it seems neither of my GPU leave idle and only GPU 0 shows any usage. WTF?

Crossfire never worked in this game before but works flawlessly in every other sim so I never really got that one, why the dev's won't enable crossfire I am not sure but I tested the vid card out with DragonAge and all is well, with riva tuner showing both GPU operating and generating heat. Thank God.

I am relieved my card is working okay but as it is RoF is borked as far as my vid card can tell.

How can I uninstall this patch or correct this bug?

Yes, I read about a new two seat bomber or something like that.

My problem is with all graphics set to either low or default my GPU will not leave idle clocks and only one GPU shows any usage. Forget about MAXing them out as I had them before and getting ~100FPS.

Now At default settings I get 15 FPS and with everything turned down about 25 FPS.

System is water cooled Rampage Extreme with Q9650 @ 4.3 Ghz 4 G RAM ATI HD 4870 X2 and velociraptor HDD. Should get better than 25 FPS at default setting one would think.

I guess I really wanna know how to roll back until this bug is fixed or the goof I am making that is right in front of me is made apparent. I have tried all combos I could considering you need to exit each time to make one.

Hi fox, I had the same trouble, see Pooch's thread here http://simhq.com/forum/ubbthreads.php/topics/3149565/1/First_Patch_That_I_m_Not_Happy.html

In my case, it was fixed by enabling Catalyst AI and setting to 'Advanced'. You can also try enabling adaptive antialialising if you don't already (prior to Catalyst 10.11 I took a big FPS hit doing so, no longer.) I have the same card as you, (my Specs are in the post) and this worked great for me.

Do you also use 'Driver Sweeper' to clear out remnants of old drivers before installing new ones? Maybe you do, just to confirm.

If you haven't tried this already, hope it helps. Smile2

Thanx Biggles07, I updated to Cat 10.11 and still cannot get frame rates back up to where they were before even only using 57% of the GPU. The new driver added about 10 FPS so I now get ~35 FPS. Thats a fifty percent decrease in performance with levels turned down. Not good.

Have you checked on your cards performance and noticed if your memory clocks rise above idle when the game runs. I have and they do not budge on my card above 507/500, they should adjust to 750/900. I am curious if others notice this or is my game in need of a new installation.

I used riva tuner, turned on hardware monitor to monitor core and memory clocks and they just flat line. Only one GPU works in this sim, I wish they could allow crossfire.

Wish I could roll back to the previous ver.

Are you sure CF doesn't work? I don't have riva tuner, but i have open hardware monitor. It doesn't show me a a graph of gpu core activity, but it does show a temp graph, and give me the min and max core usage. It shows the core heat up and remains in line with the other core, and it shows the max on both cores were at 100% after playing. I will say that I also took a big fps hit after the patch. But in my case I found it was the super sampling filter. Once i went back to multi-sampling, I seem to be back to pre-patch levels. Almost anyway. I'm a noob here, so I don't have much experience with this game, but in the few hours i had before the patch, and using the same mission as a test, I think I've only lost performance on the ground. I assume it is the new filtering for ground textures. Good luck, hope you get it figured out.

CF is enabled but yields little improvement.
Same as il2.
Run some benchmarks with cards on and off.

GPU0 shows activity in game while GPU1 flatlines. This is according to RivaTuner hardware monitor. I get a blip of activity in GPU1 when I exit the sim. I've checked with other sims and both GPU's show plenty of activity and heat as soon as the games load. I can get 35 FPS now but when I played last with the previous version I was enjoying FPS above 75FPS so I guess I got spoiled.

Running on one GPU is really not as much of a concern to me as the way I understand it crossfire really does not contribute much in the way of gameplay with RoF.

What has me concerned is the core and memory clocks do not budge off idle. Now I am not sure they ever budged before but for sure they are not moving now with this patch. They jump right to 750/900 when I load another game. I am wondering if anyone else noticed this using ATI cards or the 4870X2 which is what I am using.

It would be really be nice if we had the choice to rollback as I would not mind the gaame as it was before the recent "improvements".

Have you dropped your settings so they reflect 1.015 standards? Medium settings now is equivalent to High settings pre-patch.

I played some last night and both my cards were running hot and at 80+% throughout the game. These are 6870's, and I know they made some improvements to the cf scaling, so i wonder if that's it. Tonight, if i get a chance before i go out of town, I'll try it with cf disabled to see what the performance is like.

For reference, I play at 1920X1200 with all settings on max except med hdr. I had the light sources @ 4, but after playing around with them, i see no difference at 20. The only other thing that really screws my fps is when i use supersampling AA from the CCC. I saw single digits when it was on. (At least I think that was what did it) Anyway. In the first campaign mission, of the first campaign ("hat in the ring"?), i get about 40 to 50 fps on the ground, and once up above 1000 feet or so, they pretty much lock in at the v sync limited 60. I see some drops into the 50's when i look down at towns or heavy forest. And I must admit, i've got some newer games and this is the first one that has ever gone below that V-Sync limited 60. ( I hate tearing so I always use the vsync). So maybe it's not really taking advantage of the crossfire. I'll let you know what i see when i try it without the CF enabled. I'll be gone a few days, so i ;might not get a chance to test it until I get back.

And BTW, I've got a laptop with a intel p8500, 4 gig's of ddr3, and a 9800M pro.(vista os) How do you think it will play the game? I was debating weather to install it and take my joystick with me. it has got an HDMI hook up, and the hotel has nice flat screens. it works well with some other games i play, but this one is so demanding, i think it may not be worth the effort when it's so glorious on my home PC.


Oh and btw, my cpu specs are a 950 @ 4 gHz, with 6 gig of cas7 1600 ram, on win7 64

fox3, there is a known problem with the ATI HD4870 X2 not utilizing both cores properly. AMD/ATI has admitted to this. Try a Google search about it.

The 10.9a are the most sucessful Hotfix for 4870x2, the 10.11 Cats are actually older and don't include this hotfix...

ArgonV thank you for this heads up. I will check into this hotfix. thumbsup

Funny I was using Cat 10.9 until the patch came out and only just upgraded to 10.11 trying to figure out the loss in FPS. I have the sim running at 35+ FPS now but would love to get it back above 60FPS.

I never noticed it running on one core before as it ran very well and I had no complaints. It was only after getting huge reductions in FPS with the new patch that I started investigating and found the problem with the clocks running at idle and only one GPU active.

The 10.9a driver (hotfix) is newer than catalyst 10.11?! dizzy Now I'm really confused lol, thanks for info Argon, I'll look into it. I actually skipped both 10.9 and 10.10 (10.10 would not even install). As far as I can see there is no real benefit (at least with FPS) to Crossfire/SLI and dual GPU cards at all in ROF at present?

After lots of testing, sadly the 'black tiles' on landscape have returned when using Catalyst AI. I ran a sh*tload of missions without problem, and thought it had been fixed. Not so, and my optimism was premature. It happens very infrequently now, but once is enough. Back to disabled. We are not the only ones with probs though, I've read a lot of posts by Nvidia users saying they are having grief post patch too.

*sigh*

Biggles07, there is also a 10.10e hotfix revision, but I am uncertain if it includes the ATI 4870X2 fixes... So for 4870s as I know right now, 10.9a is the best way to go. The 10.10e has updates for only AMD Radeon™ HD 6800 Graphics series and ATI Radeon™ HD 5000 Graphics series it seems: http://support.amd.com/us/kbarticles/Pages/gpu88-catalyst-10-10e-hotfix.aspx

Here's the info from AMD concerning the 10.9e hotfix: http://support.amd.com/us/kbarticles/Pages/ATICatalyst109Hotfix.aspx

I know the 10.10e hotfix updates are not included in 10.11, which is why I said 10.11 is not the newest...

The 10.9a hotfix is for vista and win7. I have XP64 so I gave it a try and it stated that the drivers are already updated and did not install anything, I might need to roll back to Cat 10.9.

Mebbe I'll try this 10.10e first and give that a go.
