Add refresh rate option

[Kappa971]

Hi, an option to specify the monitor refresh rate would be useful, especially when using Nvidia DSR. Some games such as Splinter Cell Chaos Theory or Far Cry, but generally all older games that don't allow you to specify the monitor refresh rate, when used with DSR, will always use the lowest supported refresh rate for that DSR resolution. For example with my 144hz monitor, DSR supports 75hz, 100hz and 144hz. 75hz will always be chosen as the game doesn't allow you to select 144hz.

DSR has had this bug for many years but it seems Nvidia doesn't really care.

I'm unable to reproduce this, tried windowed and fullscreen mode.

Reproducing the problem is very simple:

1. you need a 144hz monitor, maybe a 120hz one is fine too (Freesync or Gsync I think is irrelevant) and an Nvidia video card
2. Set, for example, DSR 4x (in my case the DSR resolution is 3840x2160)
3. Run Splinter Cell Chaos Thery, check the monitor's OSD, and you will see that the monitor has been set to the minimum supported refresh rate for that DSR resolution (in my case 75hz):

Some monitors are set to 60hz.

FPS are not affected by this, unless vsync is enabled. In your screenshot, the game is running at 305fps, but I bet the monitor is running at 60/75hz. This driver problem has been around for years and has never been fixed, you will find many people on the web who have this problem. I generally use DSR only in games where other antialiasing methods fail, and they are usually DirectX9 games like Splinter Cell Chaos Theory, Far Cry or GTA 4. However, GTA 4 doesn't suffer from this because in the game menu it allows you to select the desired refresh rate.

EDIT My monitor is connected with DisplayPort.

Hm, I think it doesn't happen to me in windowed, but in fullscreen it shows 60hz/60fps(in menu)/400+fps(in game).

@Kappa971 can you try this version? d3d9.zip

@Kappa971 can you try this version? d3d9.zip

Unfortunately the game still runs at 75hz

Have you set the desired refresh rate in the ini?

[Kappa971]

Have you set the desired refresh rate in the ini?

Yes.

This is d3d9.ini:

[MAIN]
FPSLimit = 0                                   // max fps (0: unlimited/off)
FPSLimitMode = 1                               // 1: realtime (thread-lock)  -  2: accurate (sleep-yield)
FullScreenRefreshRateInHz = 144                  // overrides refresh rate selected by directx
DisplayFPSCounter = 0                          // displays fps and frametime on screen
ForceWindowedMode = 0                          // activates forced windowed mode

[FORCEWINDOWED]
UsePrimaryMonitor = 0                          // move window to primary monitor
CenterWindow = 1                               // center window on screen
BorderlessFullscreen = 0                       // borderless fullscreen windowed mode
AlwaysOnTop = 0                                // window stays always on top
DoNotNotifyOnTaskSwitch = 0                    // window ignores focus loss

This is SplinterCellChaosTheory.WidescreenFix.ini:

[MAIN]
ResX = 3840
ResY = 2160
HudWidescreenMode = 1 // Makes certain hud elements offset to screen edges.
WidescreenHudOffset = 100.0 // This is the default offset for 16:9. For lower aspect ratios adjusted automatically, for higher you may change it manually.
DisableAltTabFix = 0 // Set 1 to disable Alt+Tab fix

Ah, sorry, my bad, this is the proper version: d3d9.zip

Now it seems to work, thanks @ThirteenAG

Alright, I'll push those changes to a pull request #14 for now.
