senbon: There will always be some texture delay when moving about in games, seeing as most games are streamed (from disk to memory to cache).
To reduce loading delay when transfering texture maps from disk to memory you could:
- Be sure to have a large amount of RAM (4-6GB for most modern games) available.
(this will reduce the amount of disk access needed).
- Upgrade from a normal HDD (7200~ rpm) to a SSD (can be up to 8 times faster than a normal HDD).
- Upgrade to a faster (with multiple cores) processor (with increased cache).
Software wise you could try to exit other applications before starting The Witcher 2 (to use less ram).
Here we go again another "you need i7...SLI...144hz...32GB" kind of posts misinforming people with valid questions
Have you actually checked whether all the upgrades you listed make any difference except giving someone a massive bill to pay?!
Not bragging.
I have SSD, I5, GTX 970 SLI and 8GB (windows programs cannot use more than 4gb anyway), G-sync 144hz and have pop-in textures too. As much as I like W2 I think this is quite bad.
Not saying SSD doesn't make any difference (loading times cut significantly) but this does not help to remedy this texture pop-in problem.
