Hi guys All my games run fine at 1920 1080p 60hz but when i launch crysis in DX10 my samsung P2470HDTV switches to 24hz is there a way to fix this?
make a profile for crysis with the destop properties of catalyst set the res to what you want, then launch the profile. Don't forget to set in the application of the profile to launch crysis when you activate the crysis profile.
And what can cause switching between 60 and 30Fps in crysis, JC2 and other games?? It is not more or less but it drops to unplayable 30fps when near big scene to render PLs what is you opinion thanks
occur to me too..jc2 max setting + vsync on..locked at 30fps..need to off vsync to get 50fps and above
It happens because Crysis runs under dx10. Long story short, due to specs of DX10, compliant apps don't use video driver info about resolution and refresh rate, but get 'em straight from EDID. However, dx10 coding is quite poor in this concrete title, so it can't read multiple resolution strings and use only the first one avaliable. Which, in this case, is 1920*1080*24hz, hd-player compliant format. What's for switching to 30fps in certain places - had the same issue myself with 1080i tv connected through hdmi cable. In DX10 titles once again mostly. That is a driver optimization which turns vsync on in certain places to improve performance, mostly in open spaces. Since 1080i refresh rate is 30 hz, fps in these places gets capped to 30.
I made a profile and still get the same issue if I untick fullscreen in the game menu then I get 60hz.
Right I found it, "Run Regedit go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\Explorer\NoActiveDesktopChange s and if the value is 1 change it to 0. That should stop any 24HZ issues, including the infamous Crysis 24hz at 1080p bug. This fixed the resolution issues I was having with Crysis and Crysis Warhead. " Thanks go to Kitch9 for that.
Yes it effect PC monitors, I had to use that reg fix after every format of Win7 to stop it capping the FPS in Crysis and Warhead.
the latest fix for that for me, is to switch to 50hz in windows then start the game. then exit the game switch to 60hz and that has fixed it for me........well till the next driver that is lol
I have the same problem here and this is how I fixed it for now. http://forums.guru3d.com/showpost.php?p=3586934&postcount=217
Yes I tried it and it didnt work this is the only game that goes to 24hz as soon as I launch the game my hdtv gives me the info that the monitor swithed to 24hz all other games are fine and it doesnt happen in windowed mode only in fullscreen.
