Hammer Model Lag

When higher poly-count models are being drawn, hammer's 3D view slows down to a crawl, but only when I'm selecting something. By higher poly-count I mean average LOD models. Never had this problem on my old computer. TF2 runs on average at 200 FPS+. Not sure what to do :/

not radius culling

Make sure you dont have the radius culling enabled. Its the R with red circle around it. Disable if its enabled. Press 1 or 2 to decrease and increase draw distance, that also helps.
