ShadersMod v2.5.1 (Non-Forge Edition) for Minecraft 1.9.4
This mod requires recent and fast graphic card with NVIDIA or AMD GPU.
Intel HD Graphics drivers *.3408 to *.3621 do not work and will crash.
Intel HD Graphics driver 188.8.131.52.3945+ can run without crash but it is still slow.
Graphics effects do not come out of nowhere. They require computing power of both CPU and GPU.
Some shaderpacks render around 10 times slower than vanilla Minecraft.
You can expect low frame rate if your computer cannot get more than 200 FPS from vanilla Minecraft.
