144Hz Issues that I don't understand..

[foozball3000]

After my LG died (lasted an amazing 10 years), I replaced it with a proper ASUS.
The 144Hz is amazing for work, much less strain on my eyes. Overall, I'm quite happy with it.

But here's the part that I don't understand..
My GPU is somewhat dated, but was powerful enough to run Thief (the latest one) on full graphics, at 1680x1050 (old LG)
But when I started it up with the new monitor, even the main menu was lagging. 1680 to 1920 isn't that much of a jump.

So I started testing.
At lowest graphics settings, I get around 20fps.
But if I go back into the desktop and change the monitor to 60hz, Thief runs fluid again at 50+ fps.

To my understanding, let's make it 120Hz to keep the numbers simple, if you render at 120hz, the GPU has to do double the work compared to 60Hz. But my experience so far suggests that it's more than 4x the work?? How does that work?

I am just pulling figures out of my nose .. So if your card runs thief at 50 fps (suggest to me its almost pulling the card dead 80-90% that leaves about 10% of the gpu left. Now you want your card to run more then double the fps 120. so that 10% would need to coup with 70 more fps

vsync on or off?

The card needs an update, granted. But you'd think it will run Thief at full graphics at around 20-25fps? On it's very lowest graphic settings, I don't even get that.
On high graphics it hovers around 8.

All of this just seems wrong.. like the GPU is trying to do a lot of redundant work. Perhaps I'm missing a setting somewhere or a driver?

I don't know, can't remember. I'll test it with on and off later tonight.

What GPU is it?

Latest drivers installed?

Monitor drivers installed?

I didn't get any drivers for the monitor. It's an ASUS VG278HE 27" 144Hz.

Okay, so testing on a more updated game, Starcraft 2. With Vsync Off, I get round 150fps, whether the monitor is running at 144hz or 60hz, no real difference. Then found a setting to cap my FPS to 144 in the variables file.

Seems then the issue with Thief is still unresolved (a problem for another day). But for now I'm happy
