[SOLVED] Metal Gear Solid V Phantom Pain FPS Drops with CPU and GPU at 50%

[Inbox]

[SOLVED] The problem was the Windowed Mode was set to Borderless Fullscreen instead of Fullscreen. Thanks alcoholbob.

Good evening.

Recently I started playing MGSV Phantom Pain (1080p, all settings maxed out), but the problem is that I'm experiencing FPS losses, even when the CPU and GPU are at 50% at most.

If there is no bottleneck on the GPU and CPU, why are the constant FPS drops happening? Can it be because of the lack of vram (as each one of the GTX680 only has 2GB of NVRAM)? Even GTA V runs great with only 4GB (2+2GB) of NVRAM.

Is anyone experiencing similar issues?

Regards.

that is not 4gb of vram that is 2gb of vram. that is not how sli or cf works. your 2gb vram is probably causing it, my best guess. it is also why 970 3.5gb gives really bad min fps in certain games.

Make sure you are running in fullscreen mode and not borderless fullscreen.

Yup I know, but even so I thought FPS losses every 5 seconds were not normal, as even in GTA V maxed out, (with the suggested limits disabled) I don't experience such drops, and I've 60FPS most of the time.

Lol alcoholbob thank you so much that was the problem

I thought the game was running on fullscreen, when it wasn't. I only noticed that it was not when I was analyzing several screenshots I took just to remeber what settings to tweak and so on, and the first option was set to borderless fullscreen.

As soon as I changed it, the game is running at 60fps rock solid everything maxed out.

Regards.

very happy for you

Yep this is why I'm selling my Titan Xs and going with Freesync + Fury X. A lot of games in fact don't even have a true fullscreen mode and only have a borderless/full screen windowed mode, which completely messes up alternate frame rendering frame pacing and makes 80 fps look like 20fps.

Is there something freesync + fury would give you that couldnt get with your titan X's + gsync? or just single titan X + gsync?

FreeSync at this time does not work when games are in "Windowless Border" or "Window Mode"

Not gonna help you.

The only 4k gsync monitor is a 28" TN and that's been out almost 2 years. There are over half a dozen 4K IPS Freesync monitors > 30" alone out today and many many more announced. Monitors can take over a year from announcement to release and we haven't heard any rumors of other 4k gsync displays. Likely they won't be available until Pascal is out.

I don't want to be stuck with GPUs that are incapable of adaptive sync and also are not fast enough to maintain 60fps necessary to sync to a monitor. People already have guides how to hack Freesync monitor EDID to get Freesync coverage down from 40Hz to 31Hz.

Basically, Nvidia does not provide the performance or the features I'm looking for, so I'm going AMD.

Well we'll see. CF performance is also quite a bit better than SLI so two Fury Xs with Freesync should give a significantly more consistent performance than SLI Titan X + Vsync when Freesync is working, and when it's not it should provide comparable performance at 4k anyway.

40fps is much easier to aim for with Fury X CF than 60fps with Titan X SLI. Other than a few Gameworks games a Titan X isn't usually 50%+ faster than a Fury X, usually it's more like 15%.
