Well I voted for “Better FPS and same stutters”
And I will quantify that below, System specs: I7-920 @ stock speed 6gb of ram (3 x 2gb in 3 cannel mode) GF GTX275 (stock speed) with NV 270.51 drivers. Win 7pro 64bit (running like classic win2k desktop/folders etc I.e no XP/vista/win7 desktop/folders FX) OS & Steam on separate dedicated HDD. Running NO pagefile (I haven’t for >6 years, but it has been enabled for shutter testing on its own dedicated HDD but it makes no difference as there is >3gb free RAM that windows will use as VM before paging VM to HDD pagefile) Game settings: 1280x720 @ 60hz full screen, AA = x2 Modal detail, Damage decals, Building detail, Land detail, Visual effects = Medium settings Buildings amount, Land shading, Forest = Low Grass & Roads = On Shadows, Anti epilepsy filter = Off Quantification: Test1.trk Pre & post patch frame rate info was gathered with FRAPS using a 160sec benchmark using a repeatable .trk file of a decent from 2200ft above RAF Ford to land at RAF Tangmear (200ft) with 8 other planes circling to land, this .trk has never exhibited any shuttering either when originally flying it or subsequent replays. As above game settings: Pre patch = 8609 frames, 28 Min, 79 Max, 53.806 Avg Post patch = 9946 frames, 39 Min, 78 Max, 62.163 Avg As above game settings except for 1600x900 @ 60hz full screen, AA = off: Pre patch = 7614 frames, 26 Min, 62 Max, 47.588 Avg Post patch = 7891 frames, 31 Min, 61 Max, 49.319 Avg Test2.trk (perceived shutter testing with buildings) Pre & post patch frame rate info was gathered with FRAPS using a 160sec benchmark using a repeatable .trk file of a decent from ~2500ft to low level over a larger town which is over flown twice in opposite directions Buildings in numbers larger than a small village are about the only cause of shutter for me when flying low, given frame rate is independent of “shutter” for me, with buildings the increase in frame rate matches similar % increases to the minimums & average frame rates collected above for pre and post patch though many more permutations of building detail level & building amount were tested with the aim of perceiving shutter. A: With Building detail = Low & Buildings amount = Low Vs. With Building detail = High & Buildings amount = Low, has minimal impact on frame rate and the same amount of shutter take place B: With Building detail = Low & Buildings amount = unlimited Vs. With Building detail = High & Buildings amount = unlimited, has minimal impact on frame rate and the same amount of shutter take place, the frame rate is slightly lower than A: above (~5fps lower but we are still talking >30fps) and the shutter has a slightly different nuance to it and could be said to shutter fractionally less than A: above especially when over the centre of the town as there is a perceived smooth spot ware all the buildings are in view so have loaded. To me the problem with buildings is threefold, 1st: the mechanism in how they are loaded into the game world and when. 2nd: the amount of LOD’s used for “flying” situations when there is a lot of irrelevant detail being shown for flying at even at just above roof height but at high speed. 3rd: how setting Building detail = Low only serves to reduce the distance each LOD will be seen but NOT also the highest detailed LOD that can be seen. So e.g. on Building detail = Low with Buildings amount = Low, you get a performance hit from the quantity of buildings loading and unloading rapidly from view in a short space of time, you get a performance hit from successive LOD’s loading rapidly and a performance hit from the detail of the highest detail LOD being shown.

Patch is a generally good improvement for me.
System Specs i7950 @3.66 6 Gig 1600 Ram ATI 5970 Win 7 64 Bit Running game with: 1920x1200 (Native), No AA, Fullscreen. Model Detail, Visual Effects, Damage Decals -- High Building Detail, Land Detail, Land Shading -- Medium Forest, Building Amount -- Low Epilepsy Filter Off Grass, shadows - on roads Off A big difference for me is also having aero turned off. It improves the stutters considerably for me (unfortunately this creates some tearing when using TrackIR which triple buffer does not fix...but its not so bad and I can live with it for now). Stutters do remain however..over water in a 6x6 dogfight, when several of the opposing planes are in view as we merge. Also when really really close to another plane. ...over land, stutters whilst definitely improved are still there for me despite good FPS of 30-40 (with occasional spike up or down by 10 frames or so). I wonder if the issue for the 6xxx series of ATI cards that Luthier mentioned a possible hotfix for also affects the 5xxx series? Anyway, all in all, the patch is a good result in my view... I was able to scream over London in my Spitfire with very playable frames in a free flight whcih was awesome. I thought everything was smooth over water pre-patch for me, but since the patch, my fights over the channel are at another level now. Apart from the minor stutters mentioned above, the game is pretty much perfect over water for me now...and definitely playable over land. A full on fight with lots of planes over London may well have to wait until the SLI/Xfire fix and the multi core optimisations, but i am more than confident now the game is going to be a masterpiece. Well done Luthier and team. Keep up the good work.

Yesterday I got my new PC, therefore I can't compare but let me tell you my feelings about patched version.
New PC has i-2500k (not o/c...yet), 6gb ram, ati hd6850, ssd. I ran a couple of single missions in medium settings with grass/shadows/roads on and although it was quite smooth when I was alone over sea, it still has problems when flying over land or when close to other planes. Therefore game is still in unplayable status even in a brand new system

Game settings:
res 1280x720 full screen obj det: high effect :high decal damage: high all other: low Shadow: on grass: off roads: off We set up a server yesterday with these settings. On server in pic time were playing 16 people (was the max setting) via internet (yap it works now, it's viewable via internet) I was the host and I had with these settings max 90 fps avg 35 fps. I have to say that there were for me some microstutters for a sec only above the city and when a plane flew practical 1m over me (335th_GRAthos). The Server was playable. There were a big improvement overall. For the first time GPU-Z show utilization of GPU over 90% and the use of the memories in both my cards. A great improvement. Thank and keep the nice job!

for me no difference between the Beta and the New Patch
it seems that ATI 69XX Cards not good running with the game i have graphic errors like bridges on sea und overall 20-25 FPS at DX10_0 8-9 FPS at DX10_1 with details on LOW thats not fine for my system arma2 runs with 30-40 FPS with all sttings on High and 5000 viewdistance thats the power that other games runs on my system....

I clicked better FPS and fewer stutters.
Just getting a couple of seconds of stutters at the start of every flight. I find, particularly over land, that it's worth a quick look around the scene to load in the scenery tiles, then it's smooth after that. As far as FPS is concerned, a very measurable improvement for me. 1280x720, everything set to High. Grass, Shadows and Roads on, AAx2. Over land average fps up from 42 to 62 Over water up from 56 to 70 Over London up from a stuttering 15 to a quite smooth 48 - 59

Ive got better FPS, but stutters are the same especially down low.
Internet seach seems to take at least 7 mins to update so its still impractical and appears to be hit and miss. #Also a foot note, items such as houses and aircraft and landscape res in and out continusly, thats what is causing the stutter from what I can tell# Last edited by BigPickle; 04-09-2011 at 08:12 AM.

After this patch, things are no different on my end. At 1680x1050 with things on medium and low for building/forests, the game is still unplayable for me. Not superfast PC, granted, but I do think that it should be better. Tried it also on lower resolutions with same settings (first wide after 1024X786) and the results weren't much different. Perhaps the FPS were a bit better but then there were more stutters. So, not there yet :S
PS is: Intel C2D@3.0Ghz Geforce 8800GT 512MB 4DB DDR2 @ 1100Mhz Win7 64bit Ultimate, all updates installed Latest nvidia drivers
