I'm trying to make a pixel art game and my resolution is 384 x 224, but when I change to fullscreen the sprites looks blurry and I don't know how I can disable bilinear filtering.
I tried SamplerState.PointClamp on spriteBatch.Begin but it didn't work, I also tried this.GraphicsDevice.SamplerStates[0] = SamplerState.PointClamp and disable PreferMultiSampling but nothing works. Someone told me that it can be fixed using renderTargets, and I tried that by myself, but that didn't work either.
I used spriteBatch.GraphicsDevice.SetRenderTarget(renderTarget) and null at draw method but it still looks blurry. How do I use renderTarget? does it replace my sprite? Does it needs to be window scale or sprite scale? Help please
PD: I'm using FNA, but it seems to monogame. Is a reimplementation of XNA
