I took the winter retexture port from Rizala Zakaria, removed all unnecessary textures, left only snow, compressed it into several versions: 256x256, 128x128, 64x64. I also compressed the lods to 64x64, 32x32, 16x16. Ported vegetation from TES: Oblivion, converted and threw a couple of trees from Resident Evil 4. Reworked all textures, fixed bugs with vegetation display and shimmering palm trees, compressed to 256 and 128. All models are low-poly, you should not worry about FPS.
