I've recently been having a problem with texture loss when playing GTA 4. Basically what happens, is I'll start the game up, it will run smooth, then not too long after starting it, maybe a good 5-10 minutes, it hiccups and then lags. I move the camera around and I'll be missing buildings and roads and I can see right across to another island or through a hill. I've gone and googled some fixes but nothing seems to work. What's odd about it to me, is that it's all of a sudden happening. It's never happened before until now. I don't have many mods except for modded police cars, ELS, LCPDFR 0.95RC2 (the only one it will run without crashing), and the Native Trainer. I've uninstalled the game and re-installed it and it wont help. Anyone know of any fixes?

Does it work without mods? Have you bought the game? 

It will do it with or without. And I did buy the game.

Try ChickamruRealTraffic, dunno if it fixes the textures but it's the best traffic loader in terms of performance.

Ok. Thanks. I've been looking for a better traffic mod.
