A few things you can try: First, make sure the HDMI cable you're using supports 60Hz at 1080p (some cheaper cables can limit this). Then, check if the TV’s refresh rate is locked to 30Hz, which is pretty common on some models when connected via HDMI. Also, double-check that the TV’s settings aren’t limiting the input resolution or refresh rate. In your graphics control panel (NVIDIA), ensure that the refresh rate is set to 60Hz for the Samsung TV. If that doesn't help, try adjusting the graphics settings in Aces High to see if lowering the quality can improve the frame rate. It’s also worth checking for any firmware updates for the TV—sometimes those can resolve weird performance issues. Let me know how it goes!
