I've run the OA Benchmark with my Phenom II X4 955, 8GB RAM and HD6950 (shader unlocked) 2GB and was wondering if anyone could suggest what else might make a dramatic improvement. I haven't got anything overclocked at the moment, but can get my CPU up from 3.2Ghz to about 3.8-3.9 Ghz stable, and my 6950 from 800/1250 Mhz to 930/1375 Mhz if it will help. I started with these settings: Very High, 1280x720 Visibility 4039 All on Very High except: Video Memory - Default Aliasing - Normal Shadows - Normal HDR - Normal Post Processing - Low and in the config (defaults, not manually tweaked): 3D_Performance=93750; refresh=59; FSAA=2; postFX=2; GPU_MaxFramesAhead=1000; GPU_DetectedFramesAhead=3; HDRPrecision=8; lastDeviceId=""; localVRAM=2129182720; nonlocalVRAM=2147483647; vsync=1; AToC=7; PPAA=0; PPAA_Level=0; Windowed=0; FXAA=0; Using ArmaII Launcher I set Max Mem 2047, CPU count 4, Beta, No splash screen, Default World - empty and enabled the mod okt_noblurbeta. 1) First Benchmark - 38FPS. MAX VRAM: 1046MB. MAX RAM: 5171MB (after 3481MB) 2) V-sync Disabled (and Enabled), Radeon Pro closed: 38 FPS, Max RAM: 5352MB (3403MB after) 3) V-sync Enabled, Triple Buffering set in Radeon Pro: 35 FPS, Max RAM: 4717MB (3411MB after) 4) V-Sync Enabled, nothing enabled in Radeon Pro: 36 FPS, Max RAM: 4839MB (3421MB after) 5) Reduced Visibility from 4039 to 2010: 43 FPS 6) Reduced AA to Disabled and Post Processing to Very Low (FSAA=0, postFX=1): 48FPS, Max VRAM: 1222MB 7) AA back to Normal (FSAA=2, postFX=1): 42FPS Having Radeon Pro running does seem to cause a hit of 2-3 FPS, which offsets the gain I may have seen from using it to disable Aero. I guess I could do that manually without using RP, but it's a bit of a pain really. EDIT: Done some more tests 8) All on high except Vid Mem Default, AF V. High, AA Normal, Postprocess V. Low, Vsync diabled: 45 FPS 9) AA Disabled, Shadow Disabled, HDR Normal: 55 FPS 10) AA Normal: 51 FPS 11) Shadow Normal: 50 FPS 12) Added PPAA=3, PPAA_Level=2: 49 FPS 13) Increase Visibility to 4084: 39FPS 14) Visibility 2010, Terrain Detail Very High, Shadows High, Post Process Disabled: 44FPS So I get quite a boost (10 FPS) at 9) with AA and Shadows disabled and HDR on Normal and lose about half this with AA and Shadows back at Normal and another 10 FPS increasing the visibility from 2010 to 4084. I don't like the way shadows pop-up on Normal anyway, which they don't do on High (I understand they get processed by the CPU at Normal and the GPU at High or above) but I'll have to see if it's the Terrain Detail at V.High or the Shadows at High that's costing me 5 FPS, as I could probably live without shadows whereas I believe the Terrain Detail's quite important. I'm not sure whether Visibility at around 2000 is high enough for flying though, so perhaps someone could advise on that, as if I need to increase it I'll have to reduce something else. EDIT 2: Yep, seems it's Shadows (and AA) that are mostly responsible. 15) AA Disabled: 50 FPS 16) AA and Shadows Disabled: 55 FPS 17) Shadows High: 51 FPS 18) Shadows Disabled, AA Normal: 49 FPS 19) AA and Shadows Disabled, Visibility 4048: 42 FPS. So I still lose 13 FPS with Shadows and AA Disabled if I increase Visibility from 2010 to 4048.

Radeon Pro's quite handy if you've got an ATI card as you can set it to disable Aero when launching OA and it will re-enable it when you exit. I was looking for a "render frames ahead" setting in RP, but it doesn't seem to have that unfortunately.

I won't ;)

It's not like I've been sitting around waiting for you to answer, I've been out and about doing stuff ;) Anyway, seemed safer to check with you first before moving files around in case I'd misunderstood. Now you've confirmed, I'll test it out.

I just noticed in the Optional folder there's a oa2a2bridge_c_pvpscene and a readme for it which says "This addon allows OA Players, which are not using Arma2, or only have Arma2 instead of OA, to use this mod without any errormessages." so does this mean if I copy this and the .bisign to Addons, J.S.R.S will work fine with just OA (and continue to work with CO lite)?

Cool, thanks. ---------- Post added at 11:15 ---------- Previous post was at 11:13 ---------- Yeah, I know that it was designed for CO (and what CO means), which is why I asked if it works with CO lite! Thanks for your hard work on the mod anyway.

So I assume this isn't compatible with CO lite (i.e. OA + Arma2 Free)?
