+This article contains tips about optimizing [[doomsday]] for older hardware.
+====== Slow CPU ======
+Disabling or lowering these CPU-intensive settings will help improve performance on slow CPUs.
+  *  Disable [[3_d_model]]s.
+  *  Disable simulated radiosity ([[fake_radio]]). Set the cvar //[[rend-fakeradio]]// to zero.
+  *  Disable [[particle_effect]]s or lower the value of the //[[rend-particle-rate]]// cvar.
+  *  Disable [[dynamic_light]]s. Set the //[[rend-light]]// cvar to zero.
+====== Slow graphics card ======
+Disabling or lowering these GPU-intensive settings will help improve performance with old graphics accelerators.
+  *  Using paletted textures will save texture memory and make texture reloads less frequent. Enable with the *-paltex* option.
+  *  Disable smart filtering of textures. Smart filtering significantly increases the size of all textures. Disabling it will help conserve texture memory.
+  *  Disable simulated radiosity (FakeRadio). Set the cvar _rend-fakeradio_ to zero.
+  *  Disable dynamic lights or reduce the size of dynamic lights.
+  *  Use additive blending for dynamic lights instead of multiplicative blending.
+  *  Disable particle effects or lower the value of the _rend-particle-rate_ cvar.
+  *  Disable detail textures.
+  *  Don't use high-resolution textures.
+  *  Disable anti-aliasing in the graphics adapter's driver settings.
+  *  Use a lower display resolution.
+  *  Use a 16-bit video mode.
