What's the problem? Describe what went wrong.

Upscaling causes anything rendered in the engine POP uses (This include the Main Menu and Some Cutscenes) to drop to vary low frame rates. 8 to 15 FPS on the main menu and below 10 FPS during gameplay. The audio is also vary choppy while its rendering.

What steps will reproduce the problem?

Set the Internal Resolution to anything not "Native", Boot the game pass the logo and into the Main Menu.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Yes - [5.0-11991]

Is the issue present in the latest stable version?

Don't know, Can get 5.0 to run unlike latest development version that works find

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool and anyone who is building Dolphin on their own can use git bisect.)

[First broken version number here (if applicable)]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here:

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

  • Relates to performance changed from No to Yes
  • Status changed from New to Questionable
  • Subject changed from [Windows] Prince of Persia The Two Thrones - Broken Upscaling to Prince of Persia The Two Thrones - low performance at >1xIR

We normally don't accept performance problems (there often just isn't much we can do about them), so I'm setting this to Questionable for now.

The game is fairly demanding and has kinda glitchy opening menus that run at AS MANY FPS AS THEY CAN, and as usual this is a fucking ubisoft title so it's full of spaghetti.

Anyway, in game I can reproduce your issues, it's a demanding game but I was able to run it at 3x IR above full speed. We have another issue for Ubisoft's madness with the opening menus running uncapped.
