ini entry to force vsync in opengl

[Etern@l]

Hi,

First Great job for the ogl driver, it rocks !!

I have juste a wish

I'd like forcing vsync in ogl from a variable in the ini. Is it possible ?

I know it can be done in the driver but, shame on me, I play also Quake 3 a lot and I need vsync off in q3. I'd like not to swap the setting in my driver each time I change game.

I have set the driver (radeon 3.7) to default vsync on (application preference) with rage 3D tweaker, but it does not work with the unreal opengl patch (guess that vsync off is hard coded somewhere).

The only way to force vsync on in unreal is to set the driver on always vsync but in this case the Q3 variable can't bypass the setting and I have vsync on in Q3...

Thanks again !

UseVSync=true

Thank you SO much! I can't tell you how long I've been looking for a way to enable vsynch using this renderer without having to change vsynch to "always on" in my video card drivers. Woo Hoo!!!

Hello,

Sorry to say that UseVSync=true works only with the D3D driver, I'd like enabling vsync in openGL driver.

Thanks for the try anyway !

It works just fine for me using this site's openGL renderer. Maybe it's an issue with the 3.7 CATs. Have you tried any other drivers? I'm using the 3.5 hotfixes.

I have tried everything I can to enable VSync in OpenGL mode. UseVSync=True in the ini file, Changing swapinterval values between -1 and 3, and finally attempting to force in NVIDIA control panel. Nothing works. I simply can't get vsync here.

SwapInterval - [Integer]
Controls V Sync. If set to the default value of -1, the default buffer swapping method is used. Set to 0 to disable V Sync. Set to 1 to enable V Sync. Set to higher values for one frame every N screen refreshes. Not all video drivers support values higher than 1.

Other than that there is nothing more. Maybe buggy driver? Seems to work fine so far on any machine I tried.

Posting here to report that with 227e under linux there are problems controlling AA quality and vsync using UnrealLinux.ini file. It simply don't work no matter the values I specify in SwapInterval, UseAA, NumAASamples and AAFilterHint. Forcing AA and VSync using nVIDIA X Server Settings (driver control panel) works. Unfortunately enabling vsync seems to introduce slight mouse input lag. It is very slight but I can 'sense' it after many years spent playing 3d shooters.

Trying to use 227f OpenGLDrv with 227e leads to game starting up correctly but showing no graphical output at all (i.e. blank black screen). As 227g is (hopefully) very near this report is just an "informational" one and I will re-test the problem as soon as 227g would be available to download.

Upd. Finally got 227f to start up without sigsegv on my system and checked if the problem with enabling vsync/AA using UnrealLinux.ini affects this version too. Unfortunately it does. The only way to get 227f use vsync and antialiasing on my linux box was to force both of them with nVIDIA driver control panel.
