Whenever I activate DirectX 11, the game always starts at a 50Hz refresh rate. I know this because I use FRAPS to measure framerate and I also use D3DOverrider to force a triple-buffered vsync.
When I start the game with DirectX 9, the framerate gets locked at a steady 60 fps at the menus, but when I activate DirectX 11 and restart the game, I get a steady 50 fps at the menus (my graphic card is more than capable of rendering more than 60 fps on the menu screen, so the sudden shift to 50 fps is because of the switch to DirectX 11)
I play the game at 1080p resolution. Once inside the game, if I go to the configuration menu and change my resolution to a lower one, the game goes to a 60 Hz refresh rate. If I switch back to 1080p, the game then maintains the 60Hz refresh rate. But whenever I RESTART the game, it always starts at a 50 Hz refresh, and I have to do the resolution swapping trick every time.
When I play on a PC monitor, it isn't much of a problem, since my monitor accepts the 50Hz refresh normally. But whenever I plug my PC on my LCD TV (LG 42LV5500) the TV doesn't accept this refresh rate and switches to a 24Hz refresh, and since my vsync is on, the game also locks at a 24 fps framerate, which is unplayable (and the mouse lag also shows up)...
I've seen this issue all over the forum, people with projectors and 3D displays can't get the game to work on DirectX 11, but they didn't seem to get that these problems happen because of this 50 Hz refresh priority... The projectors switch to a 24Hz refresh rate, just like my TV. And 3D don't work because instead of doubling a 60Hz refresh to get 120Hz, the game doubles a 50Hz refresh to get 100 Hz, which probably is an incompatible refresh rate for the 3D displays...
A simple solution would be to change the refresh rate priority, so it selects 60 Hz first. And a better solution is to enable us to select the refresh rate when adjusting the graphics options... Please Crytek and/or EA, please give us this small and simple update, it will probably spare you guys a lot of other support headaches, just by implementing this fix.
This problem happens on AMD and nVidia cards (I had a Radeon HD 5850, now I have a GTX 670). It happened with all driver versions I installed.
This problem happens on my original copy of Crysis 2, with the latest v1.9 patch, the DirectX 11 update and the hi-res texture pack installed, and also happens on my Crysis 2 Maximum Edition.
Thanks for the attention, best regards,
