(Migrated from github.com)

The controller XeFG_DynamicCount.h works from the game's real frame rate, leaving out the time spent waiting in OptiScaler's limiter and present. With nothing capping the frame rate, it goes for the multiplier that lands nearest the target (Up / Down rounding pick the closest one above / below instead). Under an FPS limit or V-Sync it steps up when it falls short and steps down when one less should still hold, and undoes step downs that don't. If the target is out of reach, extra generated frames only stay if they actually add FPS. It can also drop to 1X by switching XeFG's frame generation off with xefgSwapChainSetEnabled(false). While at 1X, GetInterpolatedFrameCount() returns 0 so the limiters, menu and swapchain wrapper see it.

There's also Use target as cap (TargetAsCapDMFG). It makes the target the FPS limit as well, and a simpler controller (XeFG_DynamicCap.h) just holds it.

New [XeFG] options, also in the menu: DynamicMFG, FramerateTargetDMFG, RoundingDMFG, DynamicAllow1X and TargetAsCapDMFG.

Adds Dynamic MFG to the XeFG output. With it on, the Frame Gen setting becomes the max and the multiplier gets picked every frame to follow a target FPS. The target defaults to the FPS limit, or just under the refresh rate if there isn't one. If you want to move the ui around thats fine @FakeMichau, however if you could keep the XeFG model status that be sick and awesome. Sorry for the large commit.
