It's going to depend.
I never had a lot of problems with GTAIV to begin with because I understood how the sliders were supposed to work and I simply made sure my values "kept me in the green." Post patches it simply got even better and I was able to turn more settings up. It ran well out of the box...it runs great now post patches. Key phrase: On my rig.
I have a nice rig with a GTX280, 8 gigs of RAM, and an Intel qx9650. So obviously YMMV along with anyone else's.
Post patches, I thought SR2 ran great as well again key phrase being: On my rig. It runs WAY better post patches vs. when it first came out of the box.
Pre patches that thing had some obvious frame rate issues, stuttering, and possibly even a memory leak. I pretty much quit playing it early on until after they patched it then I more or less fell in love with it, lumps and all.
All told: Both games are much better today post patches vs. the day they came out.![]()
Right, well I think our rigs are fairly similar, and I found performance to be OK. It's not like I'm inexperienced or unfamiliar with adjusting settings either -- I kept in mind the bounds of my VRAM, and didn't go wild. I just feel that things should have been smoother given what's going on in the game, especially considering the supremely huge delta between my system's performance and the specs of the consoles.
I think given the prices for Saints Row 2 I may as well give it a try. Who knows, maybe I'll love it.
