@han_siang_wong, what resolution do you play?

 

1440P

i play in 4k, but i don't understand why in medium and high details i have practically the same fps .. it seems a bandwith problem .. can you measure this? is there any guide to getting maximum bandwith?

I play on an internal screen of an HP 840 G5 on a 2070, I get around 50-60fps in high @ 1080P. (yes even with this laptop only supplying 2 lanes) Bus usage hangs around 20%

On an external screen, I get around 70 ish. 

My numbers may be high because my CPU can sustain 3.9ghz on all cores forever and this game is very cpu heavy. 

I think I found the problem. Seems like it's only 16gpbs? I bought another TB3 cable and will arrived today. Will update here. I do hope it's the cable and not the port, if I have a half port then I am stucked.

Its a Tongfang GM5M-Aftershock Apex 15(2020) /XMG Neo 15/Eluktonics Mech 15 G3/Inifinity W5

@han_siang_wong, are you using the cable that came with core x? that's short but it's 32gbps

@manu89ft, 

I bought the core X 2nd hand so I don't know if the cable is the original one. I still at work. I will update onne I test when I am at home 

you can see the performance of the tb3 with CUDA-Z

Hmmmm seems like it is some thing to with cable at least its playable with RT Medium now... Previously its almost unplayable with RT turned off 

High difference! But was it a tb2 cable?
