Sorry about the wall of text.
So basically I’ve been a mapper for about 6 years now and throughout this time I’ve used a few different computers to do so. Recently I have acquired a new laptop for my merry adventures. The computer is reasonably spec’d, it has an Intel i7 2720QM, 6GB DDR3 RAM and a ATI Radeon 5650 and runs everything I want to just as well or better than its predecessors bar just one thing. Hammer editor is an uncontrollably laggy bastard on this machine. The camera view is jumpy and glitchy no matter what viewing mode its set to. It takes entire seconds for Hammer to register that I have in fact moved the cursor away from the x/y axis box and that it is now on the y/z box so that I can begin to shape the brush that I had just created. Loading the texture browser takes a solid 3-4 seconds and then proceeds to wait another 1-2 before any textures begin to emerge. I think from that you can understand the sort of troubles I might be having in actually mapping without becoming extremely pissed off and closing the application. I have tried everything but talking to you guys about what the problem could be. I’ve done the obvious like re-installing Source SDK and running it in windows XP compatibility mode. I have also tried the obscure things like re-downloading the all my drivers for my graphics card and processor. So now I try the most obscure thing of all and asking the good, terrible and downright genius people of facepunch for their help.
Had Hammer for years and years, get a new (higher spec’d) computer and suddenly it lags like a 9 year old playing CoD on dial up. I have tried a bunch of ways to fix it without success, help my sorry ass.
