Question about old graphics trick

Featured Replies

Quite some time ago there was a trick going around that if you changed your PC render resolution to 200 it would actually help your VR graphics.

Was the effect real? But more importantly, does it still have any relevence in 2023 or has that trick gone away?

Case: (Lian Li PC-011 Dynamic XL), PSU: (MEG Ai300p pcie 5 & ATX 3.0), Motherboard: (ASUS TUF Gaming x670E-PLUS WIFI 6E), CPU: (AMD Ryzen 7 7800-X3D) 

Memory: (G.Skill Trident Z5 NEO RGB Series 64GB DDR5 6000), GPU: (Zotac Gaming GeForce RTX 4090 AMP Extreme Airo). CPU Cooler: (ASUS ROG Strix LC RGB 360) 

Fans: (7 Corsair LL Series 120mm RGB)

I can't imagine it will help with VR performance...

It is not a "trick" - any VR game looks better if you increase the supersampling/render resolution/pixel density (different names but the same principle), as it is just a performance intensive form of anti aliasing, and because a VR display has a much lower amount of pixes per degree of your field of vision compared to a monitor, you will notice pixelation in the anti aliasing much more than a monitor. So when you increase the render resolution you improve the anti aliasing and stuff looks better - simple as that.

However, greatly increasing the render resolution has diminishing returns up to a point where you just get worse performance for not much visual improvement. Where that point is depends on your VR display and your GPU.

The trick was to increase the render value to 200 in the PC section, which somehow was going to improve graphics in the VR section. You can find threads all over the internet about it, but they are about 1-2 years old. That's why I was asking the question.

Ah ok. I haven't seen any mention of this, sorry.
