Motherboard not sharing RAM for GPU?

[Panchy]

Hi, Im trying to help a friend, it seems the GPU cant use RAM as VRAM

Specs:

GTX 1050 2GB

Asrock B550M-HDV

RAM 16GB 3000mhz (dual channel)

Ryzen 3100

 

Everytime he hits 2000MB of VRAM the frametime goes up and down and fps lower to 40s on GTA V, when VRAM is below 2000MB fps are in the 80s and frametime is stable.

 

Clearly the problem is the low vram of the 1050 but why the gpu isnt using the system memory? is this a GTA V thing maybe? how can i check if shared memory is working properly?

The GPU prioritizes it's own memory over the system memory. It will only use the system memory when it is completely out of VRAM. Using system memory is bad for gaming performance, the latency is much higher, and it is in general slower.

Well, you don't want to max out the settings of you're graphics card, system memory is a lot slower then Graphics memory like @Coolmaster said. Turn down you're settings if you want average performance.

 

Make sure FXAA is off.

I never had any problems with my 1060 3gb tho... even games that use more than 3gb of vram didnt stutter, the pc uses the DRAM and problem solved

The extra 1gb is significant. It's a 50% increase. The 2gb probably can't store critical components of the game.
