Problem with Vsynch

[TheMafioso]

In PC game when i enable Vsynch i am locked to 60fps and the framerate often go down to 30fps...

But my screen refresh rate is 75hz and in others game with Vsynch i am locked to 75fps...

Why it don't work with 75hz refresh rate but as 60hz???

[Mr_nonick]

Maybe the game defaults to 60Hz ingame.

[Skullknocker]

Lets hope that can be changed as 60hzt ain't healthy :rolleyes:

[evoke]

60hz makes my eyes hurt over long periods lol. I use catalyst control centre to force 85 in all games.

[TheMafioso]

How can I force 75hz? With control panel not work...I have a nvidia 8800

[Skullknocker]

I'de say its a game problem No matter what you force.

I have this EXACT same problem although my screen is always 85hz. However I am running vista 32bit and decided to try the game in dx9 mode by right clicking on it... and....

Yes you guessed it it works correctly under dx9 mode going to 85hz making the game play MUCH smoother because also the framerate is avaragely MUCH higher like 15-20 fps at least and with no visible difference in graphcis quality.

So IF you run Vista as well give it ago under dx 9 mode (disabling the option alone in the options menu won't do the trick I tried that as well)

[KamikaZe]

so as it seems btw this is the games fault or dx10 not working correctly.... :/

[TheMafioso]

Yes it works in dx9 mode and antialiasing also works but some textures are ugly on dx9 mode...

Dude give me one screenshot of comparison where one can noticably see the difference. Its al between your ears and right now this seems to be a bug in the game so I think in a future patch they will fix it as there is no reason why the game should have problems with v-sync in dx10 mode

[TheMafioso]

Okay no problem i will do it but please do you know something for skip intro??? It take a lot of time for nothing to always wait for this slow intro!!!

Well... that's a problem i don't have with using DX9 mode. Dunno what is causing that but it can't be the DX9 mode as it works fine here and that's why I said why there is no visible difference between dx9 or dx10 as it should be like that

as it should NOT be like that

*damn the no edit button :mad:

[TheMafioso]

I'ts maybe only when you force AA in dx9 mode???

[KamikaZe]

Dunno I didn't force AA so you could try it without if you have done so.

[TheMafioso]

Yes but if i use dx9 it's for aa and synch but aa is very important for me

[TheMafioso]

So if dx10 isn't better with graphics it's useless??? Why developpers put it in game?

Sorry if that has been posted elsewhere, but the refresh rate of the vsynch can be changed in the demo.

Go into your BioShock demo folder then navigate through Builds and Release. Locate the config file Default then open it with notepad or a text editor of your choice.

Look for the section [D3DDrv.D3DRenderDevice] if your using DX9 or [D3DDrv10.D3DRenderDevice10] for DX10. Under both of these sections there is the option to change the refresh rate, DesiredRefreshRate=60 is what its defaulted to. Change the number to the desired refresh rate and voila.

Hope that helps anyone thats having problems with the vsync.

I've found another simple temporary workaround for the DX10-VSync-60FPS-30FPS-Problem:

Simply ALT-Tab out of the game and back in, et voila, your frames won't dip magically to 30 any longer. Checked with Fraps on my 8800 GTX. You'll only need to do this once while being in the game.

Hope that helps for now.

This is an issue with DirectX. Download Refresh Force and set your overrides.

And if you are getting the 30-60-30-60 thing when using vsync, it means that triple buffering is disabled. Open the Nvidia control panel, go to manage 3d settings and set triple buffering to enabled. The game still has to support it though, which Bioshock does, but you still have to allow it in the driver.

Huh ok... I didn't knew that I will try it out as I have that exact problem in DX10 mode. I don't understand anyway why this happens only under dx10 mode :/

This doesn't work for me. If I do that the game opens up in windowed mode and crashes afterwards :( Thanks for the tips though. Glad to read I am not the only one with these things

[KamikaZe]

Hmm I tried the tripple buffering but it doesn't do a thing for me :/ Still have the 60 - 30 fps error

Hmm still got to use the dx9 mode I am affraid.

Best fix I can find is my own, lol.
