1.5.2 Performance Issue

Can you please take a look at the KA-50 Convoy Hunt single mission?

I updated to 1.5.2 little bit ago.

Something does not seem quite right here. I flew that mission many times in the previous builds, and did not see performance this low.

First I will say, I tried the cold start instant action mission, and it was awesome - frame-rates like 190 fps with 99% GPU usage. I was like wow, this is incredible, performance has gone way up.

So I loaded up the attack convoy single mission, first thing I notice on the runway at the start, my frame rates were like 30 fps. I took a quick glance at my video card monitoring, and it's core speed was maxed out as it should be.

But, the GPU usage was only like 35%.

As I progressed into the mission, the GPU usage would slowly climb to eventually like 70%, giving me around 70 fps.

The cold start mission however, stayed around 99% with awesome framerates.

I tried it with both true full screen ( alt+enter) and not, was the same.

Was not sure if this would be an actual bug, but I have flown that mission so many times in the previous builds, this one stuck out at me like a sore thumb...

Thanks,

How did you update? My updater still doesn't show any new updates.

Same here. I keep hearing of others having it but mine is quiet. I'm wondering if they are doing some sort of rolling update to different areas to prevent server overload?

Did you use

Command Prompt Window,

Type: DCS_Updater.exe update

Additional observation:

In this same mission, F2 exterior view at the start on the runway the GPU usage immediately goes up to 99% and 150 fps, drop back to cockpit view, GPU drops down immediately to 35% and 30 fps.

Edit: no scratch that, that was in exterior view looking straight on the chopper, once I panned it around in F2 view and was looking ahead, the gpu usage dropped like a rocket and frame-rates went down to like 35%... strange.

Maybe it was doing this in the previous 1.5 build, but I really do not think so - don't recall ever seeing frame-rates that low in 1.5 and I flew this mission many times over. It is obviously directly related to the GPU usage it is seeing. Video card running full bore on core and memory speed.

Hope this information is helpful.

still didn't work. Mine wont update at all.

Mine neither

Just a thought (I don't have the KA-50), have you tried loading that mission into the editor and then saving it back out into a temporary location and then trying that version? Perhaps it needs updating for 1.52?? Might be worth a try.

Have not given that a try yet, not very familiar with the ME just yet, will take a look at it tomorrow , wife and I heading out for a night out here soon.

Thanks,

I´ve tried the same mission before and after 1.5.2 update.

Exactly the same FPS in both test.

45-48 over the runway. Solid 60 FPS flying everywhere. Maybe the parking Hinds and Il-76 take a little tool over FPS until you left the runway.

Wow. TGP making big fps hit since update. Just making note. GTX 780, 16 gigs ddr3 Core I7 950 windows 10 64bit trac ir5 G940

Yes TGP/Shkval is FPS killer.

No FPS hit on the TGP here

I'm also experiencing performance issues.

same here. As its not a big hit I definitely got a overall hit on different missions with different modules of a stable 80 to 90 fps to 60 to 70

Haven't downloaded the update yet, will see how well my super powerful 360 noscope 420 MLG gaming 4K HD6570 graphics card will respond to this update.

I think the clue on this one would be in the GPU usage numbers and why it is so low at the start of the mission ( 35%). Obviously the lower that number the lower the fps.

I do not remember the exact numbers in this mission in prior build, but am confident it was not that low.

As mentioned earlier, in the cold start instant action, my GPU usage was like 99% and fps were very high. Whereas at the start of this single mission ( Attack Convoy), it starts out at like 35% and fps in the cellar.

I just don't know enough about the actual gpu usage numbers and how a game relates to that being utilized to understand what might be going on.

I just know that there is a significant difference in the performance in this particular single mission, compared to flying it in the prior build.

It is as noticeable as the difference in the Cold Start instant action mission, except in that one it was the other way around, my fps skyrocketed in that particular mission ( and gpu usage was very high).

Well I messed around with it a little more and nothing seemed to really make a difference.

I guess I will just leave it with this observation:

1.5.2 seem to offer significant performance improvements in some areas, when the GPU is being utilized fully the framerates are splendid. Way higher than I was getting in 1.5.1 in certain missions. But it may be the framerates were capped in 1.5.1 and was just not displaying the full potential as well.

Likewise, performance in other certain missions has declined. Seems to be directly related to the much lower GPU usage for that mission.

I do not know if any of this would actually qualify as a bug, but am hopeful the feedback is at least helpful to the devs.

This update Kill my FPS and Sttuterings..:mad:

I can not believe it, When working in Beta, is perfect! when they make the leap to 1.5.2. break all :doh::doh:

incredible
