Title: From 60 to 9 FPS?
Post by: PR3D4TOR on February 19, 2017, 05:30:56 PM
What gives? :confused:
From 60 to 9 FPS on a 4 GHz 8-core CPU and a GTX 1080? Some serious buggery going on here. All graphics option set to default, shadows and post lighting disabled.
Anyone else having FPS drops like this?

Were you over a super large airfield with a flak base near by?
I found in cloud front testing with DX9 that my FPS would drop from 60 to 47 while at a super large airfield with a heavy cloud front going over with tracers going off all over the place at the 6 drones. DX11 would make it a bit better. Then I removed the high stratus layer and my FPS was back to normal.
What terrain was this and what field or fields were you over?

This was 30 minutes ago over/near a knit airfield. I'm running the dx11 version. I have Nvidia's FPS counter on and it dropped to 9 around the time I got the oil hit.

that is the super large airfield like bustr mentioned

Was just flying here. Multiple reports of lagging. I had La7 lag back and forth 400 out which threw me off and made it frustrating. There were a decent amount of folks there. Not sure if it was a spike but many people reported it over radio.

dx11 is still buggy. use dx9 you will be ok.

Dx9 is too CPU intensive. For some reason AH only uses one of my eight cores.

I have the same issue when I'm flying near ports or a CV but my FPS indicator still shows 59-60fps but the game becomes a slide show.

Not a dx11 only issue. Happens to all sorts of folks, both versions. Some with quite powerful PCs.
I posted this bug a couple weeks after ah3 went live, with little feedback here. Fly around these large bases online and the complaints on radio range are numberous.

What 8 core processor are you talking about?
Title: Re: From 60 to 9 FPS?
Post by: Dobs on February 19, 2017, 09:56:19 PM
FX-8350 clocked to 4.5 GHz. It's not the fastest around anymore (hasn't been for at least three years if not more) but it's still equal to a 3 GHz i7 core for core. It's next on my upgrade list, but I'm waiting for the Ryzen.

I avoid those large fields like the plague I suffer major hits also but have the time the good fights are there

If the game is only using one core, it is due to the workaround AMD provided for detection of CPU's which do not have thread safe high resolution timers incorporated into them.

Do you mean the HPET? The FX-8350 most certainly has HPET. After all the technology was developed jointly by AMD and Microsoft.

Nope. Many AMD CPU's did not include high resolution timers for each core. AMD provided a work-around for applications which depended on them. The work-around was to test for the existence of working (key word there, means more than just being available) high resolution timers for each core, and if they were not available, then tell the application they are not available.
Again, this work-around was provided by AMD.

If you have overclocked that CPU every since you have had it, I would say all bets are off.....

Yes, thanks TC, that is one I forgot about. That can impact the high resolution timer usage.

Nah, with custom water cooling I'm keeping it cooler than at stock clock speeds and air. Barely require any extra voltage for such a modest overclock. If I wanted to I could push 5 GHz with this setup, but I wanted the CPU to last a while and kkep temps and noise to a minimum.
That's interesting Skuzzy. Even on just one core I normally get 200-500 FPS with Vsync off. It must be something about that big base that's just not right.

It just means you are probably going to see a wider swing in the frame rates and stutters (little ones) could be more prevalent.

Not to get to technical here, running a CPU clocked higher than the factory clocked settings even if your CPU came unlocked so it is capable of being overclocked
Opens the door for the "high resolution timer for each core", to become unstable and hence AMD's provided work around to engage, when the timers fall out of sync with each other...the timer tolerance is very close to something like "1 tic or lesser" going from my aging memory
Hope this helps

Easy enough to check. I just loaded up the default CPU settings running everything at stock. AH still uses only one core. Never had this issue with other games, even Bethesda's poorly optimized mess of games manage to use all my cores. Still it matters not, since one core is clearly enough to run AH at 60+ FPS except over these problem bases, and my CPU cannot possibly affect all the other players having FPS drops over these bases...

Not all games need or make use of high resolution timers.
Title: Re: From 60 to 9 FPS?
Post by: PR3D4TOR on February 20, 2017, 12:06:33 PM
Ok. Out of curiosity, why do you use them?
Title: Re: From 60 to 9 FPS?
Post by: Skuzzy on February 20, 2017, 12:12:51 PM
The answer to that could come very close to some of our IP. Close enough I do not feel comfortable answering it. It would be up to HiTech to answer that.

Outside of what Skuzzy posted, Aces High is a game that deals with having to deal with massive math calculations just for a single aircraft flying, heck, just show them the picture of all the wing pressure points that are being calculated in reference of that "Stall thread" as well as airflow, torque, thrust, etc.... then combine that with the atmospheric arena settings and multiply that by the number of players playing
Gives you a little look in to why those "high resolution timer for each core" is needed, because of HTC's strong desire to make each plane fly as close to the real thing
Hope this helps

I use dx9 and my frame rates dropped to over half..couldnt even play..all this happened last night ..all the times before everything was fine

Ive noticed then frames only drop during and shortly after tracer fire. Other than that..I have no issues.

I used DX11 for months until I started spiking and getting frame freezes and had to go to DX9. Last night the performance around large basis was terrible even with settings dialed down. It had to be one of the patches.
