DCS writes quite a few temp files, god knows why. Worth a try!

Great! I think the new drivers only cater to their newest cards, screwing up older models. To make you shop and is exactly what Windows/Intel and Apple crime syndicates are doing.(((

Could you look in the task manager how much RAM does your DCS use?

@raptorsim: My sig is clear: 8Gb DDR3 Ram, 2Gb vram, no SLI. I tested everything at low and reported earlier in this thread "no improvement". I also reported that looking away from MFDs in FLIR/MAV modes still bears FPS hit and that I see a significant CPU utilization drop when turning these modes on. So my conclusion is that the videocard has nothing to do with that. I have ordered more RAM, to up it to 16Gb and will report... and I don't see any memory leak...

Did you try assigning your TEMP and TMP folders (both user and system variables) to a RAM drive? I did it ages ago, helped me with DCS stutters. It is also great to delete all the crap various programs leave )))

What's your memory usage with DCS? Mine is 4.1 with 1.5 free, BUT pagefile at 6.7... UPD: Ok, that high pagefile usage was reported by MSI Afterburner. Windows PerfMon shows a mere 5% of 8Gb allocated. Still curious what others see... UPD2: Disabling pagefile did not make a differene to FPS. Afterburner still shows I'm using 6.7Gb of it (LOL), while PerfMon won't even allow to add the measure to the chart. I did order 8 more Gb of memory, will update when it arrives...

Do all the guys who see improvement from 1.5.1 have 16 Gb of RAM?

I further noticed that FLIR/MAV kill FPS even when I look away from the MFDs. I suspect that the bug is not video related, but some algorithmic bottleneck. CPU utilization drop may be an indicator of this.

Funny thing just happened. I finally risked upgrading my video driver from 332.21 to 358.91. Yes, my driver was 2 years old, but anything newer was giving me random BSODs at the time, so I rolled back. This menu screen with clouds used to run at 130 FPS, but now only at 19! 19, Carl!!! In game FPS are 5-10 lower as well. I did a proper wipe with DDU, all video settings stayed the same. Way to go, Nvidia...

Your pilot has cold! ))

Nope! )) Same smoke happened in free flight mission...

I did, nice! But I still like Diveplane's mod better...

1.5.1 open beta Exhaust smoke I like the idea! Maybe at low airspeed and high revs it is realistic to see such a thick smoke behind BF 109 (MW 50??). BUT at high speed on idle it should not be visible. And when landed, if visible, it should go up or stay near the plane, not go back (no wind)! It just stays in the air as a fixed object, even after the engine is off... And it is definitely a disadvantage in a dogfight when P-51 does not smoke!!

Don't know if reported, I see a weird bug on my TGP in the WHOT mode. The border between light/shade in the cockpit is now rendered as a thick black line. On my stills it may appear as a distant river or a cloud shadow over water, but it was moving independent of the terrain... Also, the trees and buildings are now really flickering in FLIR!

No! If anything, updating to 1.5.1 reduced my baseline FPS from 110 to 85, and FLIR+Mav from 50 to 40. Ran the test twice... I use quick-easy-fall mission on active pause from the first second. Why, DCS, why? Edit: loss of baseline FPS was due to No Tree Shadows mod being removed by the update. Now restored, but the "FLIR problem" is still very much there ((

Mig-21 reactivations After the latest open beta update, Mig-21 said my system changed significantly and asked to reactivate. I am now down to 7, although never changed anything since I bought Mig-21. Not even Windows updates... With this speed I will soon have to buy it again.

Dear SiThSpAwN, Was your TGP in FLIR mode? I attached a track file turning FLIR/IR MAV on and off for a few seconds. I placed Task Manager on top of the game to watch the CPU usage. Hopefully, you'll see what I see: when IR modes are on the CPU usage goes noticeably down! This must indicate some bottleneck causing our FPS drop. flir test.trk

Which birds did you try it with? It does not work with Huey or Mig-15/21 for me...

I just noticed a curious fact, maybe it will give a clue to the devs at what's going on. When the MAV and TGP pages are up on the MFDs, the CPU utilization goes DOWN! And so does the FPS... I select some text pages, and the usage, and FPS go back up. Why?? The game is in active pause, nothing else changes. Please try on your PC.

Maybe because you've capped your FPS? Also, did you try FLIR or only MAV?

- A few valuable info like 1024 resolution for MFDs, only in FLIR mode etc. is in the posts, so does everybody have similar experience (FLIR only)? Only WHOT or BHOT modes and IR MAV give problem. Drop from 90 to 40 in Quick-Easy Fall on active pause. TGP by itself (TV mode) only steals 5 FPS. Increasing Clutter from 0 to MAX reduces baseline FPS to 75 AND further to 65 with TGP (TV mode) Changing Visibility Range from Ultra to Low made no difference - Any difference when changing resolution for MFDs? 512 cockpit or 1024 every makes no difference - How much video RAM? 2gig - Preload radius in combination with less than 2GB Video RAM? 150,000 or 100 makes no difference - Any similar virus scan or "Security suite" in use? Microsoft Security Essentials - Anything else that is special or unusual about your PC setup or that you think may be related? No - DOF Off To be fair, I see similar effect in the version 1.2! But my baseline FPS is lower at 60, and it drops to 40 with FLIR+MAV... UPDATE: I also tried all settings at Low/No, FPS still drops from 135 to 62! flir test.trk

I have Allied Flight Reports disabled in settings, but they still arrive on ACG server! Moreover, the same message plays over and over every two seconds. Like: "Enfield 1 RTB at 3000... Enfield 1 RTB at 3000.... Enfiend 1 RTB at 3000.... Enfield 1 RTB at 3000...". Mega annoying! Also, my Subtitles are unchecked, but I still see them...

I noticed the game now takes too long to render new scenes! I use snap views a lot, to zoom in, up, left, right glances. in 1.2 all is fine. in 1.5, while my average FPS is higher, I often get 1-2 seconds(!) freezes when look around. All settings high, except Civil Traffic, Clutter and Depth of Field to off... More so near ground, like in Huey missions (((

+1. FPS drop 50% with FLIR ((

The fence in 1.5 is there (pic. 1), but almost invisible. In 1.2 I can see in clearly (pic. 2). What bugs me more in both versions, is the transparent landing pad at some angles! I see the supporting construction through it (((
