General performance with my somewhat decent laptop.

[Halde]

Hi all!

 

So I'm playing Skyrim on a laptop. Which, admittidly, sucks. But I have(had, currently reinstalling STEP due to my computer deleting everything) problems with ILS ingame.

 

My computer specs are:

CPU: i7-4702MQ 2.2GHz overclocking at 3.2GHz

8GB DDR 3 RAM

GPU: NVIDIA GeForce GTX 760m 2GB VRAM

 

I installed basically all the STEP mods(2.2.8), except for some of the gameplay and audio mods, and then some mods outside of STEP. Like 20 mods that wasen't STEP mods.

But I feel like I should be able to pull STEP off. In many of the STEP guidelines to the texture mods, it generally only raises concerns when the GPU are below or at 1GB VRAM.

Generally, I would ILS if I loaded a game, in which, I was outside of in the Skyrim world. I could then walk out from wherever I was and into the Skyrim world, and then load the most recent game(if the most recent game was infact in the outside world of Skyrim).

I should note I was NOT using Skyrim Flora Overhaul or Skyrim Realistic Overhaul, but I was using the 2k version of Skyrim HD.

 

How can this be:/?

Use the Sheson memory patch (either SSME or Script Extender 1.7 alpha)

What kind of laptop do you have (brand and modelnumber)? :)

Acer Aspire V3 - 772G

Okay. Gtx 760m is a pretty good gpu for a laptop (I have a gtx 765m, which is actually just a factory-overclock gtx 760m). I don't know how much you know about how a gpu function, so here it comes :)

 

The real problem with the gtx 760m (and 765m) is that it's only have a memory interface with a 128bit bandwidth.

 

Try to imagine the 128bit bandwidth as channel, where every 64bit of bandwidth represent one channel between the gpu and the memory (vram). Then the gtx 760m has two channels where information can flow between the gpu and it's memory. For example the radeon hd 5850 (old mid-range desktop gpu) has a 256bit memory bandwidth and only 1 gb vram, but because the gpu has 4 channels (4×64) instead of only 2, the information flow between the gpu and the memory happens a lot faster. As a consequence information between the gpu and and the memory, in the case of of the gtx 760, is queuing at the channels (Creating a bottleneck), which courses framedrop, stuttering and low fps when the gpu handles large textures, antialising and suchlike (Forget about playing with enb).

 

The conclusion is that dispite the gtx 760m and 765m have 2gb of gddr5 vram (and other good features) the low memory bandwidth of the gpu is actually cousing the cards amount of vram to be pretty useles.

 

My advise (I have done every possible research in to the matter) use performence friendly effects and skip most of the 2k textures (even interiors) and you will have a nice modded skyrim :)

 

Ps. Do not overclock your Acer laptop, it does not have the amount of capable cooling needed for an overclock.

 

One more ps. English (and especially the grammer) is not my native languages :)

Wow, thank you very much. I completly understand what you are saying:)

 

I have completed my install now, using Skyrim HD Lite over Skyrim Realistic Overhaul, which I actually like more as well. I have optimized them as well. So I'm running between 25-35 FPS outside and a steady 60 FPS inside, as I previously did. And load times are like ~20 seconds!

That's great!

 

Thank you all!
