Input LAG in 4K

[StifflersMoM]

Hi!

 

I recently upgrade from HD to 4K. But now i do have Input Lags. 

My TV is set to Game-Mode with 144 hz. But i cant set my PC to 144 Hz. Only 6 Hz in 4K. When i set it to 120Hz the resolution is set to HD

 

I have no idea what the problem is. My GPU is a Nvidia GTX 1080TI

For start the 1080ti is not capable of running 4K at 144Hz. It's a 7 year old GPU, back then 4K at over 60Hz was a pipe dream. Not sure about your other settings, but make sure your video cable is 4K/144 compliant. If you're seriously considering running 4K/144 with quality settings you'll have to upgrade your GPU to at least RTX 3070ti or 4070. And don't neglect the CPU, you'll probably need to modernize that as well.

Intel Core i5-6400 Skylake Prosessor, on a MSI Z170-A Pro, Socket-1151 with a MSI GeForce RTX Ventus 2X 4070 SUPER OC is my current cab setup.

 

The MB and CPU is just about keeping up. 

 

BBB with all the settings maxed, blue light enabled - will get me in trouble during multiball for sure. Turning it off, seems to resolve it. 

 

Dark Chaos by Apophis is another special case. That table I run only on upstream 10.8.1 DX10. I highly recommend that you don't install that as default. But, for special - troublesome tables, maybe extract the latest to its own folder and manually start it. It is very improved in many ways, but, also break more than what I guess a regular user would accept. AGAIN - don't use that as default, it is NOT ready !

 

Tables that has heavy script usage, IE - VPW releases, will demand more of the CPU than what we used to. This because they are "fixing" physics by scripts. Scripts is CPU related, and currently (but, being looked at) it is quite bound to how fast the CORE that it runs on is. So, it doesn't really matter much if you've got 70++ cores. What matters is the speed of that CPU core used. But, THAT MIGHT CHANGE - I should add. Currently though, a limitation.

 

So, a fairly new, faster than my old crap CPU, with a GPU ... like what @robertms accurately described, is what you would need to get a smooth 144Hz experience.

 

4K is a HUGE amount of data to process - 4 times as much as regular HD, and on top of that ... please show me the frames almost 3 times as fast. You see the math here ?

It turned out, that my TV did not switched correctly into Gaming Mode. So now its fine. It runs on 4K with 60Hz. Thats fine and it feels really good
