P3D v5 - microstutters in full screen mode.

Postby Vishal » Tue Aug 25, 2020 5:41 am

Hi all,
I ve just installed P3d V5 (5.0.31....) and noticed that it microstutters in full screen mode ( at 30 fps stable). However, she is very smooth in windowed mode ( same fps).
I have applied the necessary tweaks to nvidia inspector ( like fps limited to 30, half refresh rate, etc).
In-game fps set to unlimited and v-sync On.
Settings are not crazy high, but I can run stutter free in windowed mode.
Applied the affinity mask in the cfg file.
It ruins the experience in full screen mode but, in windowed mode, so smooth.
I remember flying in V4.5 just a few days ago. No issues whatsoever.
Any idea guys?
Thanks.

Your CPU - i7-7700 HQ - is the issue. It runs at a base clock rate of 2.8 GHz, which is actually below the minimum required rate for v. 5 of 3.0 GHz.

In windowed mode it will run smoother, because there isn't that much graphics to update.

Hi Jorgen,

I tested it out to determine whether my CPU was the bottleneck.
I dialed down the graphic settings all the way but even then, micro-stutters did exist in full screen mode.
Again smooth in window mode.
Then, the turned the settings back up ( a lot higher ).
The same results followed.

Vishal,

Your CPU is not only the bottleneck, it is simply not powerful enough to run v. 5. That is why you get the stutters.
